Dustin Updike, Ph.D.

How do stem cells maintain pluripotency -- the capacity to become other cell types in the body? Can our ability to regenerate after disease or injury be improved with the ability to switch on and off cellular pluripotency?

To answer these and other questions, the Updike Lab derives cues from quintessential stem cells found in the germline. Germline stem cells (GSCs) are the precursors to oocytes and sperm, and these cells must retain their stem cell attributes so that fertilized embryos can give rise to all of the cell types of each subsequent generation.
