Recovery Act Funds Expand Studies of Stem Cell Biology

In theory, iPS cells could generate any type of cell and be used to treat diseases. But to realize this potential, scientists need a much better understanding of iPS cells' fundamental properties and how to efficiently derive cells that are safe for therapeutic uses.
To speed iPS research, NIGMS has awarded one-year grant supplements to 22 scientists at 16 institutions in 12 states and the District of Columbia. The investigators already have strong records of accomplishment in a range of research areas and will study iPS cells in varied biological systems.
"Stem cell biology is poised for rapid advances, and we expect our Recovery Act investment to have a catalytic effect. The new awards will contribute to the field's progress by enhancing the utility of iPS cells as tools for research, for testing the effects of drugs on human tissues and ultimately for patient-specific treatments," said NIGMS Director Jeremy M. Berg, Ph.D.
The Recovery Act funding will allow the scientists to address such important questions as:
-- How does reprogramming work?
-- What factors are necessary to create iPS cells efficiently and safely?
-- What drives iPS cells toward a desired cell type that can be used to regenerate or repair damaged tissues in a patient?
-- Do iPS cells differ from embryonic and adult stem cells, and if so, how?
The investigators receiving supplements are:
-- Bruce Beutler, Scripps Research Institute, La Jolla, Calif.
-- C. Anthony Blau, University of Washington, Seattle
-- Richard Cerione, Cornell University, Ithaca, N.Y.
-- Stephen Dalton, University of Georgia, Athens
-- Sharon Dent, University of Texas M.D. Anderson Cancer Center, Houston
-- Andres Garcia, Georgia Institute of Technology, Atlanta
-- David Gilbert, Florida State University, Tallahassee
-- Margaret Goodell, Baylor College of Medicine, Houston
-- Brenton Graveley, University of Connecticut Health Center, Farmington
-- Jeanne Lawrence, University of Massachusetts Medical School, Worcester
-- Jeannie Lee, Massachusetts General Hospital, Boston
-- Shaohua Li, University of Medicine and Dentistry of New Jersey/Robert Wood Johnson Medical School, Piscataway
-- John Lis, Cornell University, Ithaca, N.Y.
-- Nancy Maizels, University of Washington, Seattle
-- Sergie Nekhai, Howard University, Washington, D.C.
-- Sean Palecek, University of Wisconsin-Madison
-- Arnold Rizzino, University of Nebraska Medical Center, Omaha
-- Hannele Ruohola-Baker, University of Washington, Seattle
-- James Thomson, University of Wisconsin-Madison
-- Yi Wang, Baylor College of Medicine, Houston
-- Jeffrey Wilusz, Colorado State University, Fort Collins

The spatial and temporal dynamics of proteins or organelles plays a crucial role in controlling various cellular processes and in development of diseases. However, acute control of activity at distinct locations within a cell cannot be achieved. A new chemo-optogenetic method enables tunable, reversible, and rapid control of activity at multiple subcellular compartments within a living cell.
