Epidermal stem cells reside in the lower part of the epidermis (stratum basale) and are attached to the basement membrane through hemidesmosomes. Epidermal stem cells divide in a random manner yielding either more stem cells or transit amplifying cells. Some of the transit amplifying cells continue to proliferate then commit to differentiate and migrate towards the surface of the epidermis. Those stem cells and their differentiated progeny are organized into columns named … WebThese data suggested that iPSCs can be differentiated into fully functional keratinocytes in vitro, and 3D skin equivalents can be generated using keratinocytes derived from iPSCs.
