Not all stem cells are of equal interest for clinical applications‚ because they are not able to become different specialized cells. Fetal and adult stem cells are undifferentiated cells‚ which can be found within fetus or in adult tissues or organs. They have

    Follicle Stem Cell Niche and the Function of the Rac1 protein within the niche. Abstract: An adult stem cell’s niche is responsible for the preservation of the stem cell’s undifferentiated state through either intrinsic or extrinsic expression of specific proteins (Scadden‚ 2006). Situated in the bulge of the hair follicle‚ hair follicle stem cells (HFSC) are quiescent in nature and are responsible for not only its self renewal but also in the production of rapidly proliferating cells. These cells
