Newswise Four scientists from the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have received a National Institutes of Health (NIH) Director's New Innovator Award that will forward revolutionary stem cell and neuro-science in medicine. The four UCLA researchers were among only 50 scientists nationwide to receive the New Innovator Award, the most of any institution represented.

Each recipient received a $2.3M award for their respective projects. These included Dr. Reza Ardehali, assistant professor of cardiology, for his research investigating novel ways to use stem cells to regenerate heart tissue; Dr. Elissa Hallem, assistant professor of microbiology, immunology and molecular genetics, for her work studying interactions between animal parasites and their hosts to foster the further understanding of human parasitic diseases; Dr. Sririam Kosuri, assistant professor of chemistry and biochemistry, for his project developing new biological system technologies to solve outstanding problems in gene regulation; and Dr. Lili Yang, assistant professor of microbiology, immunology and molecular genetics, for her work developing a new method to track special immune cells for use in new cellular therapies.

"These New Innovator Award grants are an important acknowledgement of our cutting-edge research and will help our faculty drive the revolutionary advances we are seeing in stem cell and neuro-science," said Dr. Owen Witte, professor and director of the Broad Stem Cell Research Center. "Every cellular therapy that reaches patients must begin in the laboratory with novel ideas and experiments that will lead us in new directions in medicine and ultimately improve human life. That makes these awards invaluable to our research effort."

The NIH Director'sNew Innovator Award is designed specifically to support unusually creative investigators with highly innovative research ideas at an early stage of their career. The award seeks to support exceptionally creative new scientists whose research complements ongoing efforts by NIH.

Dr. Reza Ardehali: Unlocking the Secrets to Regenerating Heart Tissue

Dr. Ardehali's cutting-edge work focuses on both human embryonic stem cells and induced pluripotent stem cells, known as human pluripotent stem cells (hPSC), to provide insights into the mechanisms involved in the differentiation and specification of heart cells. hPSC have the unique ability to become any cell type in the body. His lab recently identified several novel surface markers that can highly enrich early cardiovascular progenitor cells. When delivered into functioning human hearts that are transplanted in laboratory conditions, the progenitor cells integrate structurally and functionally into the host myocardium. These studies established the basis for future hPSC-based cardiac therapy.

Dr. Ardehali and his colleagues were also the first to directly measure limited division in the cells that make up heart muscle (cardiomyocytes), proving that cardiomyocytes divide and that such cell division is rare. This discovery resolves an important controversy over whether the heart muscle has the power to regenerate and is critical for future research that may lead to regenerating heart tissue to repair damage caused by disease or heart attack.

His 2013, California Institute for Regenerative Medicine (CIRM), the state's stem cell research agency, New Faculty Physician Scientist Translational Research Award allowed Dr. Ardehali to initiate the preclinical studies on stem cell based therapies for heart disease that were pivotal for his success in the 2014 New Innovator Award competition. The NIH grant affirms the critical success of the project-to-date, and emphasizes the creativity of Dr. Ardehali's research and its potential to have a significant impact on the creation of novel regenerative approaches to treat heart disease.
