Researchers have found that a chemically synthesized compound, blebbistatin, can help prevent cell death in human pluripotent stem cells. These cells are of interest to stem cell scientists working on finding therapies for spinal cord injuries, Parkinson's disease, burns, heart disease, diabetes, arthritis, and other ailments. Another advantage of using blebbistatin, say the researchers, is that no human- or animal-derived materials is needed for coating the culture surfaces.
