Stem cells have the potential to become any type of human cell. Once developed, these cells can replace damaged cells in the body and help grow new, healthy tissue. In his work with non-embryonic stem cells, Stephen Dalton is unlocking that potential.
 
Dalton was the lead author of a 2012 study that solved the riddle of how pluripotent stem cells are transformed into a distinct type of cell. For years, scientists across the globe have studied these non-differentiated cells, harvested from adult tissue, but their research yielded conflicting results. Dalton sorted out the molecules that send signals to stem cells and untangled how their complex interaction controlled the cells’ development.
 
Dalton’s research makes it easier and more efficient for scientists to create cells to cure degenerative diseases or repair acute injuries. For example, new cardiac cells could be used in patients with heart disease; new pancreatic cells could be transplanted into patients with diabetes; and new neural cells could be used to repair brain injuries.
