Alan Trounson, president of the $3 billion California stem cell agency, says he is "optimistic" that some stem cell treatments developed in California will prove successful in humans in the next five years.

Trounson was quoted in The Sacramento Bee today in an opinion piece written by David Lesher, government affairs director of the Public Policy Institute of California. Lesher provided something of an overview of the agency, including pluses and minuses. He wrote,

"Those who speculate say that the most advanced stem cell treatments are still probably a decade away from becoming available to patients. And the cost to get them there will far exceed California's $3 billion investment."

But Lesher, a former political writer for the Los Angeles Times, also wrote,

"...(T)he president of the state's stem cell agency said he is 'optimistic' that at least a few California treatments will prove successful in humans in the next five years."

Lesher said,

"That may mean a genetically modified stem cell treatment to cure AIDS, (Trounson) said; it may mean a treatment that eliminates the need for some diabetics to monitor or inject insulin; there might be a treatment to restore eyesight to those suffering from a major cause of blindness.

"'These are the kind of things we need to get through,' he said. 'I hope that we have a number of them showing proof by 2015 or 2016. I'm optimistic. The caveat is that nothing is guaranteed.'"

The stem cell agency will run out of cash for new grants in 2017 and will go out of business shortly thereafter unless voters approve another multibillion dollar bond measure or it manages to secure private financing.

Lesher discussed the difficult financial environment for private financing of stem cell therapies and how it has changed since the the stem cell agency was created by voters seven years ago.

"The hope was that California's bond (financing for CIRM) would jump-start a biotech industry by building the laboratories and seeding early research to a point where private support would take over.

"But that point of commercial viability is a moving target as private investors have grown more risk averse and the regulatory path for such radical new therapies is unpredictable. So the biggest question today in the stem cell field is not whether the science will work someday. The big questions are how will we pay for it, how will regulators know when it's ready and when will it happen?"

Lesher said,

"The problem is that even the most advanced experiments in (CIRM's) translational portfolio are still a couple of years away from the same point in the regulatory pipeline where high cost and uncertainty forced Geron out of the field. And there is still no clear answer about how to resolve those same challenges, although the cost-benefit calculation will be different for other treatments."

Lesher concluded,

"Unlike high-speed rail, which continues to have strong support from the governor, the stakes surrounding California's stem cell investment have been largely invisible. That's too bad, because stem cell science is a much smaller investment for taxpayers with a greater possible return."

Our comment? In what CIRM Chairman Jonathan Thomas has declared as a "war" for public support, today's piece in The Bee was a bit of a victory. Although the article did mention difficult issues, it was generally upbeat about CIRM. The piece focused on the wonders of the science and bypassed many of the negatives about CIRM, including its built-in conflicts of interests and its reluctance to correct long-identified problems. Also absent was a discussion of how CIRM signed a $25 million loan agreement with Geron only three months before the company abandoned its clinical trial. That omission could be considered a PR plus for the agency. Overall, however, the folks at CIRM should be pleased by the article.

The state of California plans to sell $2 billion in bonds next Thursday, but the California stem cell agency, which is entirely dependent on state borrowing, will have to wait until later this spring to see more cash.

J.T. Thomas, chairman of the stem cell agency, said he expected to see CIRM benefit from the next bond sale in April. The agency currently has sufficient funds to operate until about June, plus an arrangement with the state for continued funding if a timely bond sale is not completed.

The $3 billion stem cell agency was created in 2004 through a ballot initiative that authorized its funding through the sale of state bonds over a 10-year period. The interest on the bonds raises the total cost of the agency to taxpayers to about $6 billion. Likewise, the cost of a $20 million grant is actually more like $40 million.

Financially beleaguered California's interest costs have sharply increased in recent years as the state has borrowed $53.8 billion from 2007 to 2010. This year, interest costs will come to about $5.4 billion, nearly 6 percent of the state budget. Nine years ago, it was $2.1 billion or 2.9 percent, according a piece by Randall Jensen (no relation to this writer) of the Bond Buyer newspaper.

The expense of borrowing shrinks the amount of state money available for public schools, helping the medically indigent and other state purposes.

Next Thursday's bond sale will go to refinance debt at lower rates. This year, Gov. Jerry Brown and state Treasurer Bill Lockyer plan to sell only $5.2 billion in general obligation bonds, roughly one-fourth of what the state issued in 2009.

Qatar Conference Center

If our readers in the Middle East are looking for a first-hand assessment of the state of stem cell research, they might want to take in the four-day conference this week in Qatar, which features the president of the $3 billion California stem cell agency.

Alan Trounson is one of a number of international stem cell notables at the session at the new Qatar Conference Center in the tiny nation in the Persian Gulf. The country is putting on the conference as a means of developing its own stem cell research capabilities.

Qatar had a gross national product of $129 billion in 2010, with a per capita income of $138,000, according to the U.S. State Department. The population is about 1.7 million, more than 75 percent of whom are foreigners with temporary residence status.

In addition to Trounson, other California and CIRM-connected researchers are speaking at the conference in the Qatar center, which just opened in December.  They include David Baltimore, Nobel Laureate and a former director of the stem cell agency. A company Baltimore co-founded, Calimmune, of Tucson, Az., is sharing in a $20 million CIRM grant. Other CIRM grant recipients or representatives of recipient companies appearing at the conference are Irv Weissman of Stanford; Deepak Srivastava of the Gladstone Institute, and Ann Tsukamoto Weissman of Stem Cells Inc. of Newark, Ca.

Social activities at the conference include sand dune "bashing" in off-road vehicles, camel tracking along with a look at their "robot jockeys" and a visit to the original Arabic Oryx farm.

The $3 billion California stem cell agency should shut its doors when its cash runs out in about six years and turn over development of stem cell therapies to industry and academe, the San Jose Mercury News said in an editorial on Saturday.

The piece in the leading newspaper in California's Silicon Valley was headlined, "Stem Cell Institute Should Take a Bow (Out)."

The newspaper wrote,

"This state is in financial crisis with no full recovery in sight. Bankrolling the next phase of research would come at the expense of other critical state services, including public education, that are state government's core mission and already are starved by budget cuts. It would be a mistake to pile more debt onto the state's already heavy bond obligations, which are paid off from the same general fund that pays for schools and other services. Medical research is important, but it is not at the heart of state government's mission. Bond measures now need to deal with water supplies and other looming crises."

The editorial said CIRM has provided a "strong foundation from which universities and companies can move toward cures."

But the newspaper concluded,

"Cures remain elusive -- there is never a guarantee with scientific research -- but the 10-year start voters approved was meant to be just that. The promise of stem cell treatments now must be kept alive with funding from industry, academic institutions and private foundations and philanthropists."

The editorial comes as the seven-year-old agency is driving to turn research into therapies that can actually be used in treatments. At the same time, CIRM is considering asking California voters to approve another multibillion bond measure in the next few years, a proposal that seems to be fresh news to many in the media.

The San Jose newspaper covered the stem cell agency with some detail in its first year of operation. In the last few years, however, the paper's coverage has been all but non-existent, like most of the news media in California.

Earlier this month, the paper published an overview of the agency, which highlighted the discussions by former CIRM Chairman Bob Klein about another bond issue, along with the fact that the cures promised by the campaign of 2004 have not materialized. The proposed bond issue is old news for most persons who have followed CIRM; the plan has been around publicly for more than a year. But the call for more cash comes a surprise to many of in the media. And to the public. So it is likely to pop up again as other news outlets re-visit the agency from time to time.

The presence of another electoral campaign also imposes a different sort of burden on CIRM – something quite removed from such matters as the basic biology of stem cells. It means that the stem cell agency's endeavors are being evaluated in a political context, which involves such questions as whether its actions are designed to generate the millions in campaign contributions necessary to win a statewide election or whether it is neglecting valuable research for something that will instead generate a high profile result for the benefit of the campaign but not add much to the science.

It is all part of tactics and strategy involved in the "communications war" that CIRM Chairman Jonathan Thomas discussed with CIRM board members last June in his bid to win election to his post.

The $3 billion California stem cell agency has handed out 454 grants since its inception in 2004 but what does it all mean?

Stem cell researcher Paul Knoepfler took a crack at an unusual analysis a couple of days ago, generating a word cloud from the titles of all the CIRM grants.

Writing on his blog, the UC Davis scientist and CIRM grant recipient said he was surprised by some of the results, including how small the word "induced" was in the cloud considering the hooha over induced pluripotent cells. Knoepfler also wrote,

"I found it fascinating that the next top word was 'differentiation.' As much as we all focus on stem cells in their native state, clearly the differentiation of stem cells is critically important."

Knoepfler used a free, word-cloud forming utility(Wordle) to generate the results, which Amy Adams, CIRM's communications manager, called "cool."

Advanced Cell Technology, which has unsuccessfully sought funding several times from the $3 billion California stem cell agency, drew some attention today in a piece in a Massachusetts newspaper.

The Worcester Telegram took a look at the firm, headquartered in Santa Monica, Ca., with labs in Marlboro, Mass., in the wake of Geron's departure from hESC research. The move left ACT as the only firm in the country with an hESC trial and perhaps with a better shot at CIRM funding.

Reporter Lisa Eckelbecker wrote,

"Advanced Cell, publicly traded since 2005, has spent years developing its technologies. The company brings in little revenue and has an accumulated deficit of $180.9 million. About 1.6 billion shares of Advanced Cell common stock is outstanding, a result of numerous financings over the years. It trades for about 10 cents a share on the Over-the-Counter Bulletin Board, an electronic exchange for small companies. No analysts from major Wall Street banks report on the company.

"The company's treatment for Stargardt's macular dystrophy and dry age-related macular degeneration — the treatment that required (a) mountain of paperwork before the FDA — first went into the eyes of patients in July in Los Angeles. The retinal pigment epithelial cells, generated from embryonic stem cells, were developed to slow the progression of the eye disorders, which can lead to blindness."

ACT moved its headquarters to California following the passage of Prop. 71 in 2004, the ballot initiative that created the California stem cell agency. The company said at the time it expected to "gain significant momentum by being able to take advantage of a favorable environment for funding."

ACT initially landed in Alameda, Ca., but has since moved to Southern California. Its official opening in 2006 in Alameda was attended by the state treasurer and at least one CIRM official, according to the company. The firm has never secured funding from the stem cell agency, which does not release the names of rejected applicants. However, the California Stem Cell Report carried an item in 2008 that pointed out that a researcher for ACT complained publicly about a reviewer's conflict of interest in connection with an ACT application(see here and here). At the time, Robert Klein, then CIRM chairman, brushed off the complaint. The journal Nature has also reported that ACT has applied unsuccessfully several times for CIRM awards.

It is a fair bet that ACT was an initial applicant in the round that provided funding to Geron last spring. However, by the time Geron's application went to the full CIRM board, the other applicants had withdrawn – the first time such an event had occurred at CIRM.

Since Geron pulled out of the hESC business last month, it is likely that ACT and CIRM have opened fresh discussions, given their mutual interest in producing a stem cell therapy. CIRM also has a new chairman who is familiar with ACT. After Geron was awarded its $25 million loan from CIRM last May, the agency's board elected as chairman a Los Angeles bond financier, Jonathan Thomas, who led an early round of financing for ACT in 2000. Thomas last summer sold his remaining 17,046 shares in ACT for $3,239. Thomas said he had a "significant loss" on the sale but did not disclose the amount.

Geron's flight from hESC and ACT's perserverance come as the stem cell agency is pushing aggressively to drive research into the clinic. Plus CIRM needs tangible results that voters can understand if CIRM is win ballot-box approval for continued funding in the next few years. The agency will run out of cash in about 2017 and is considering mounting a campaign for another multibillion bond issue.

The end of the year is a traditional time for the media to come up with lists of both the dubious and meritorious events and personages of the year. This year's nominations from a California stem cell researcher include Geron, Roman Reed and the new chairman of the California stem cell agency.

Paul Knoepfler, a stem cell scientist at UC Davis and one of the few stem cell scientists who blogs regularly, today revealed his awards for 2011. They ranged from the political cartoon of the year to the stem cell scientific issue of the year.

Geron was named in the "misstep of the year." Knoepfler wrote,

"You guys really screwed up by dropping your stem cell program in this manner. I believe this bordered on the unethical. I commend the actual stem cell scientists at Geron, but the person(s) who as leaders pulled the trigger on killing the stem cell program did wrong."

Roman Reed was named "stem cell activist of the year." Reed is the man who came up with the CIRM motto several years ago, "Turning stem cells into cures." He has long been active on stem cell issues, along with his equally hard-working father, Don Reed.

Jonathan Thomas, the relatively new chairman of the stem cell agency, was named "stem cell leader of the year." Thomas was elected chairman of the agency in June, replacing Bob Klein, who stepped down. Knoepfler wrote that Thomas "has impressed the stem cell community and made some very positive changes at CIRM to make an awesome organization even better."

Knoepfler has much more,  including the stem cell biotech of the year –
Advanced Cell Technology of Santa Monica, Ca. – which Knoepfler said has two hESC trials on track and an "impressive scientific leadership." Not to be overlooked is the stem cell scientific issue of the year – "warts" or genetic changes -- at least possible ones involving iPS cells. Knoepfler points out that the subject has drawn a vast number of citations in journal articles.

We should not forget the stem cell blog of the year, which came in as a tie between Stem Cell Network of Canada and Stem Cell Assays by William Gunn of San Diego and Alexey Berseney of Philadelphia. Knoepfler also mentioned the CIRM Research Blog, overseen by Amy Adams, and the California Stem Cell Report. Knoepfler said the California Stem Cell Report "is read by a who’s who of the stem cell world, and is a source of important information about CIRM," although Knoepfler said he wished the blog was more balanced "in terms of positive and critical stories." However, Knoepfler did note that several more positive items have appeared recently, but this analyst warns of the perils of excessive exuberance.

If you want to serve on the Institute of Medicine panel examining the $3 billion California stem cell agency, you have a chance during the next few weeks.

The panel has lost a member because of a conflict of interest and is now engaged in the process of replacing him. The IOM will consider both expressions of interest and suggestions for candidates. Currently, the panel has no member from California, which leaves it minus an important perspective.

Christine Stencel, senior media relations officer for the IOM, told the California Stem Cell Report that the IOM expects to fill vacancy by its meeting Jan. 24 in California.

David Scadden of Harvard resigned from the IOM/CIRM panel earlier this month because of his ties to Fate Therapeutics of San Diego, which lists him as a scientific founder.

Persons interested in serving or nominating candidates can email Adrienne Stith at Astith@nas.edu.

ISCO Collaborations Accelerate

Last week, I told you about International Stem Cell Corp.'s (OTCBB: ISCO) new European subsidiary, ISCO Europe. That announcement closely followed an announced alliance with a leading Indian provider of corneal transplants. Now ISCO has announced that it has entered into a distribution agreement for its Lifeline brand of human cell culture products in India.

Jeffrey Janus, senior vice president of operations of ISCO and CEO of its subsidiary Lifeline, said in a press release, Sristi Biosciences is part of one of the most experienced biotechnology companies in India and the first to advance cell therapy into human trials in that country. Their network among academic and corporate researchers and experience and capacity to import and handle primary cell cultures, media and growth factors in India will be highly valuable for Lifeline to continue the international commercial expansion of its brand.

A blogger on the web site of Los Angeles television station KNBC today supported a new multibillion bond measure for the California stem cell agency but with an interesting qualification.

Joe Mathews, author and a senior fellow at the New America Foundation, said the new bonds should be backed by a tax on the people and companies involved in the business of health care. He wrote,

"New stem cell moneys can't come out of funds that would otherwise go to other programs."

Mathews said voters "probably" shouldn't approve another multibillion dollar bond measure for CIRM that is paid back through the state's general fund. He wrote, however,

"(T)hat doesn't necessarily mean there shouldn't be another stem cell bond. California's major universities have invested in stem cell research, with help from the agency.

"Major researchers have relocated to the state. And the unknown nature of stem cell research's promise, while frustrating efforts to justify the research dollar for dollar, argues for doing more to learn more.

"What the state budget picture does require is that any stem cell bond should have a clear funding mechanism -- a specific tax or new revenue source (some sort of levy on companies and people involved in the business of health care) -- that would be more than enough to pay back any bond."

Mathews is co-author of "California Crackup: How Reform Broke the Golden State and How We Can Fix It," which declares that the initiative process is one of major fault points in California government. The initiative was used to create the $3 billion stem cell agency in 2004, making it immune from normal state government accountability and locking in funding that cannot be touched by the legislature or government despite any other financial needs of the state.

Melanoma-initiating cells identified by study by Krista Conger, News release, Stanford School of Medicine, June 30, 2010. Excerpt:

Scientists at the School of Medicine have identified a cancer-initiating cell in human melanomas. The finding is significant because the existence of such a cell in the aggressive skin cancer has been a source of debate. It may also explain why current immunotherapies are largely unsuccessful in preventing disease recurrence in human patients.

The news release is about this publication: Human melanoma-initiating cells express neural crest nerve growth factor receptor CD271 by Alexander D Boiko and 11 co-authors, including Irving L. Weissman, Nature 2010(Jul 1); 466(7302): 133-7. [FriendFeed entry].

A blog post about this same publication is: Stanford scientists identify a melanoma-initiating cell by Krista Conger, Scope blog, Stanford School of Medicine, June 20, 2010.

See also a commentary about the publication: Cancer stem cells: Invitation to a second round by Peter Dirks, Nature 2010(Jul 1); 466(7302): 40-1. Excerpt:

Boiko et al. study a type of human skin cancer called melanoma and, in particular, cancer cells enriched in a stem-cell marker called CD271. They find that, unlike other cells from the same tumour, CD271-expressing (CD271+) cells could initiate and maintain tumour growth in vivo — an observation consistent with the existence of a melanoma-cell functional hierarchy.

This finding reflects a view different from that of an earlier study by Quintana et al.[3], which demonstrated that, in some cases, as many as 50% of human melanoma cells have tumorigenic potential. In addition, no marker tested identified a tumorigenic subpopulation. The authors[3] concluded that the frequency of cancer cells that can initiate tumorigenesis depends, in part, on the assessment techniques and assays.

Another news item, based on the same publication, is: New hope in fight against skin cancer as deadly 'master cells' are identified for first time, Mail Online, July 1, 2010. Excerpt:

However Dr Alexander Boiko, who made the discovery at Stanford University, said the newly discovered 'stem cells' in advanced skin cancers were often missed by conventional immunotherapy.

'Without wiping out the cells at the root of the cancer, the treatment will fail,' he said.

Comments: Boiko et al. and Dirks suggest reasons why results different from those of Quintana et al. were obtained. One possibility is that the melanomas that the latter authors studied were at an advanced stage. If, as a cancer progresses, more cells acquire the attributes of cancer stem cells, then advanced melanomas may contain very high frequencies of tumorigenic cells.

As Boiko et al. point out in their publication, "The most crucial test of the tumour stem cell hypothesis is that markers or pathways restricted to tumour stem cells can be targets for curative therapies in the patient, which has not yet been done."

Isolation and killing of candidate chronic myeloid leukemia stem cells by antibody targeting of IL-1 receptor accessory protein by Marcus Järås and 10 co-authors, including Thoas Fioretos, Proc Natl Acad Sci USA 2010(Aug 30). OA article. [Epub ahead of print][PubMed citation]. Abstract:

Chronic myeloid leukemia (CML) is genetically characterized by the Philadelphia (Ph) chromosome, formed through a reciprocal translocation between chromosomes 9 and 22 and giving rise to the constitutively active tyrosine kinase P210 BCR/ABL1. Therapeutic strategies aiming for a cure of CML will require full eradication of Ph chromosome-positive (Ph(+)) CML stem cells. Here we used gene-expression profiling to identify IL-1 receptor accessory protein (IL1RAP) as up-regulated in CML CD34(+) cells and also in cord blood CD34(+) cells as a consequence of retroviral BCR/ABL1 expression. To test whether IL1RAP expression distinguishes normal (Ph(-)) and leukemic (Ph(+)) cells within the CML CD34(+)CD38(-) cell compartment, we established a unique protocol for conducting FISH on small numbers of sorted cells. By using this method, we sorted cells directly into drops on slides to investigate their Ph-chromosome status. Interestingly, we found that the CML CD34(+)CD38(-)IL1RAP(+) cells were Ph(+), whereas CML CD34(+)CD38(-)IL1RAP(-) cells were almost exclusively Ph(-). By performing long-term culture-initiating cell assays on the two cell populations, we found that Ph(+) and Ph(-) candidate CML stem cells could be prospectively separated. In addition, by generating an anti-IL1RAP antibody, we provide proof of concept that IL1RAP can be used as a target on CML CD34(+)CD38(-) cells to induce antibody-dependent cell-mediated cytotoxicity. This study thus identifies IL1RAP as a unique cell surface biomarker distinguishing Ph(+) from Ph(-) candidate CML stem cells and opens up a previously unexplored avenue for therapy of CML.

Scientist Stuart Orkin of Harvard, who headed the grant review group of the California stem cell agency for three years, today was named as a member of the blue-ribbon Institute of Medicine panel conducting an examination of the perfomance of the $3 billion enterprise.

Orkin left the grant review group in November of 2008. The IOM posted information about Orkin today but did not mention his earlier connection to CIRM. The grant review group makes the de facto decisions on grants by the stem cell agency.

During Orkin's tenure, the agency began to come under fire from businesses for what they said were deficiencies in the grant review process.

Orkin replaces David Scadden, also of Harvard, who  resigned from the IOM-CIRM panel in December month because of his ties to Fate Therapeutics of San Diego, which lists him as a scientific founder.

Here are the verbatim statements from James Harrison, outside counsel to the California stem cell agency, and John Sladek concerning Sladek's conflict of interest and resignation as chair of the agency's grant review group.

Harrison made these initial remarks first and provided a few other details later.

"While preparing the public summary for Basic Biology III (grant round)applications, CIRM staff discovered that Dr. John Sladek was one of several co-authors on scientific publications with a researcher who was listed as a consultant on a CIRM grant application.
"This is a technical violation of CIRM's conflict of interest rules, which prohibit a member of the Grants Working Group ("GWG") from participating in the review of an application if the member has co-authored papers with a salaried investigator listed on a CIRM application within a three year window.

"It should be noted, however, that Dr. Sladek's participation in the review of the application would not have constituted a conflict of interest under the Political Reform Act's conflict of interest standards because Dr. Sladek did not have a financial interest in the application. In addition, the amount of funding involved - approximately $3,000 of salary per year for three years, less than one percent of the total award - was not material, and Dr. Sladek did not stand to receive any financial benefit from the application. Finally, Dr. Sladek's participation in the review did not affect the outcome because the application was not recommended, or approved, for funding.

"Nonetheless, in the spirit of setting an example of strict compliance, Dr. Sladek tendered his resignation from the GWG."

Sladek's response to a question for comment:

"Mr. Harrison’s account  is accurate and there really isn’t anything to add other than I was pleased to serve CIRM and California  for several years and wish them well as they pursue such an important mission with respect to the potential for therapeutic applications to human disease and disorders. Thank you for your inquiry."

Selective targeting of neuroblastoma tumour-initiating cells by compounds identified in stem cell-based small molecule screens by Kristen M Smith and 16 co-authors, including David R Kaplan, EMBO Mol Med 2010(Aug 18) [Epub ahead of print][Full text]. Abstract:

Neuroblastoma (NB) is the most deadly extra-cranial solid tumour in children necessitating an urgent need for effective and less toxic treatments. One reason for the lack of efficacious treatments may be the inability of existing drugs to target the tumour-initiating or cancer stem cell population responsible for sustaining tumour growth, metastases and relapse. Here, we describe a strategy to identify compounds that selectively target patient-derived cancer stem cell-like tumour-initiating cells (TICs) while sparing normal paediatric stem cells (skin-derived precursors, SKPs) and characterize two therapeutic candidates. DECA-14 and rapamycin were identified as NB TIC-selective agents. Both compounds induced TIC death at nanomolar concentrations in vitro, significantly reduced NB xenograft tumour weight in vivo, and dramatically decreased self-renewal or tumour-initiation capacity in treated tumours. These results demonstrate that differential drug sensitivities between TICs and normal paediatric stem cells can be exploited to identify novel, patient-specific and potentially less toxic therapies.

A study led by scientists at The Hospital for Sick Children (SickKids) reveals a new method of identifying drugs to treat children suffering from fatal cancers for which an effective treatment has not been found. Rather than developing a new drug from scratch, which is a complicated and time-consuming process, they tried a different approach: in the lab, they tested existing drugs on cancer stem cells from young patients with neuroblastoma, one of the common cancers of infants and children.
