This study found that keratinocyte stem/progenitor cell-conditioned medium significantly enhanced hair growth in mice and increased the proliferation of human hair follicle cells.

This study found that stimulating the olfactory receptor OR2A4/7 with cyclohexyl salicylate promoted human hair growth and increased progeny of hair follicle epithelial stem cells in an ex vivo setting.

This study found that the cosmetic olfactory receptor agonist cyclohexyl salicylate may stimulate hair growth and expand stem cell progeny, suggesting potential as a cosmetic adjuvant for hair loss.

Stem cells are in deep skin layers, while differentiating cells are in shallow layers.

This study found that keratinocyte stem cells in mouse skin are closely related to side population or BCRP1-positive cells based on their localization and marker expression.

This study found that the CD44(+) ALDH(+) population of neonatal human keratinocytes exhibited enhanced stem cell properties, including significantly increased long-term epidermal regeneration and multipotency, compared to unfractionated cells.

This study identified specific markers that can distinguish between stem cells in different regions of human scalp hair follicles, offering potential strategies for cell sorting and purification based on these markers.

CD200 is not a reliable marker for identifying stem cells in all skin types.

In human hair follicle cultures, this study found that cyclohexyl salicylate, an OR2A4/7 agonist, promoted hair growth by delaying catagen development and expanding epithelial stem cell progeny, suggesting its potential as a non-drug hair loss treatment.

This review examines the location and markers of hair follicle stem cells, finding that they are primarily located in the bulge region and can contribute to various skin structures, but challenges remain in distinguishing them from their progeny.
