What happens to a stem cell at the molecular level that causes it to become one type of cell rather than another? In studies that mark a major step forward in our understanding of stem cells' fates, scientists have traced the stepwise developmental process that ensures certain stem cells will become T cells -- cells of the immune system that help destroy invading pathogens.
