ability to self-renew and become specialized cell types
Stem cell function refers to the ability of stem cells to self-renew and differentiate into various specialized cell types. This means they can both replicate themselves to maintain the stem cell pool and transform into different types of cells needed for growth, repair, and maintenance of tissues, including hair follicles. This dual capability is crucial for regenerative medicine and understanding conditions like alopecia, where hair growth is disrupted.
