RhoGTPases are small molecules that control a wide variety of signal transduction pathways. Their profound function in regulating the actin cytoskeleton is well recognized. Stem cells are unique in their ability to self-renew and produce progenitor cells that can differentiate into specialized cells. RhoGTPases influence stem cell morphology and cell migration as well as stem cell self-renewal, proliferation, transplantation, homing and differentiation. In this review, the multiple roles of the RhoGTPases in stem cells are discussed.
