Just as there are times when two heads are better than one, there are times when two labs are better than one. Thanks to the new Doerr Stem Cell Challenge Grants, teams of postdoctoral researchers from different USC labs have received up to $10,000 in funding to pursue interdisciplinary one-year projects. Two teams used the funding to study how to regenerate after a heart attack or injury, and how cell migration can cause newborn defects.
