This review analyzes the impact of different preparation methods for platelet-rich plasma, human follicles stem cells, and adipose-derived stem cells on hair regrowth and wound healing, but reports no new results; the authors emphasize convincing evidence of positive outcomes despite protocol variability.

This study found that activating CB1 receptor signaling in human hair follicles increased stem cell proliferation while reducing differentiated cell survival, suggesting CB1's role as a survival stimulus for epithelial stem cells.

This study discovered that the gene Tfap2b identifies a melanocyte stem cell population in zebrafish, essential for regenerating melanocytes with multi-fate potential into adult pigment cells.

This study found that aging in the epidermis disrupts cytokine balance and stem cell function, which may contribute to broader tumor-suppressive mechanisms.

This review examines how epigenetic dysregulation affects adult stem cell function, noting that impacts range from minor to serious disruptions in tissue homeostasis and potential cancer development.

This study explored the complex roles of niche cells in regulating hair follicle stem cells, identifying specific cell functions such as signaling, sensing, and relaying messages, which could provide insights into treating hair loss conditions like androgenetic alopecia and alopecia areata.

This study reports previously unrecognized cellular complexity in growing mouse incisors, suggesting species-specific differences in cell dynamics between mouse and human teeth related to growth and differentiation.

This study found that androgens inhibit hair follicle stem cell differentiation by disrupting the Wnt signalling pathway in dermal papilla cells, but Wnt activation can restore differentiation.
