This study suggests that exosomes derived from dermal papilla cells, especially those cultured in three dimensions, promote hair growth and regeneration by enhancing follicular cell activity.

This study highlights that the mammalian target of rapamycin complex 2 (mTORC2)-Akt signaling axis is essential for hair follicle stem cells to return to their niche and regenerate effectively by regulating metabolic pathways.

This study found that using 3D Gel-C6S-HA scaffolds seeded with VEGF165-modified rat hair follicle stem cells enhanced angiogenesis and vascularization in tissue-engineered skin, improving wound healing.

This study reported that disrupting ephrin-Eph interactions in adult mouse skin doubled cell proliferation in the hair follicle and epidermis, suggesting ephrins as negative regulators of proliferation.

This study suggests that apigenin may stimulate hair growth by downregulating TGF-ß1 gene expression in human epidermal keratinocytes and promoting hair follicle elongation in a rat hair follicle culture.

This study found that leukocytes and beard hair follicle cells have an endogenous circadian clock, with PER1 and PER3 expression possibly serving as biomarkers for assessing individual biological clock traits.

In this study, Geranium sibiricum L. extract promoted hair growth in vitro with human dermal papilla cells and in vivo in mice, outperforming minoxidil by proliferating cells and stimulating growth factor expression, suggesting its potential as a hair growth treatment.

This review discusses the emerging roles of transit-amplifying cells in tissue regeneration and cancer formation, highlighting their significance beyond a mere transitional state in hair follicles and the hematopoietic system.
