Sanford-Burnham researcher Stuart
Lipton is seeking to overturn rejection of his application for a $5
million grant from the California stem cell agency, declaring that
reviewers misinterpreted the proposal and relied partly on
"grantsmanship" instead of science.

Lipton's proposal deals with strokes
and is one of 22 rejected by CIRM's reviewers in a $95 million
round that comes before the agency's directors next Thursday.

Lipton's letter to CIRM yesterday said
some of the reviewers' criticism was "completely unfounded,"
"incorrect" or "in error." The two-page letter
went into specific scientific detail.

In a cover letter to the CIRM board,
CIRM President Alan Trounson said Lipton's appeal was "without
merit." He did not go into details but said CIRM staff is
prepared to discuss it next Thursday.

The scientific score on Lipton's grant
was not disclosed by CIRM, but it appears to be between 62 and 53.
Two grants ranked at 53 were approved by reviewers. Appeals from
rejected scientists are included in the agenda material presented by
the board, but the board does not have to act on them or discuss them.
Researchers can also appear before the board to make a case.

Kristiina Vuori, president of
Sanford-Burnham, is a member of the CIRM board. She will be barred
from taking part in any discussion of Lipton's application or voting
on it.
