This study found that stem cells can temporarily act as non-professional phagocytes during hair cycle regeneration by clearing apoptotic cells through a process requiring local lipids and retinoids for activation, providing insights into their dual role in maintaining tissue integrity.

This chapter reviews the biology and regulatory mechanisms of epidermal stem cells, emphasizing their heterogeneity and roles in skin homeostasis, cancer, and aging, without reporting new findings.

Keratinocytes might turn into stem cells, but more research is needed to confirm this.

Hair follicle dermal stem cells help control hair growth timing by regulating signals at the hair germ–dermal papilla interface.

This study confirmed the presence of specific stem cell populations in SKH1 hairless mice skin, including CD34+/α6-integrin+ cells, which are important for investigating ultraviolet radiation-induced carcinogenesis.

This study found that Stat3 deletion in certain skin cells led to increased differentiation and altered stem cell behavior, suggesting its significant role in skin tumor development and keratinocyte migration.

In this study, Stat3 activation in transgenic mice led to a decrease in stem cells in the hair follicle bulge, suggesting its crucial role in epidermal growth and stem cell maintenance.

This study reports that tissue-engineered skin using ES cell-derived epidermal stem cells and collagen sponge successfully healed full thickness skin defects in mice, forming epidermis and structures resembling glands and hair follicles.

This study found that selective adhesion to type IV collagen successfully enriched human hair follicle stem cells based on distinct adhesion properties and marker expressions.

In this study, murine fetal epidermal stem cells successfully formed new hair follicle structures when cografted with folliculus pili cells in nude mice.

This study found that deleting the ATR gene in adult mice led to rapid onset of age-related traits such as hair graying and osteoporosis through reduced regenerative capacity.
