This review discusses the therapeutic effects of stem cell therapy in various diseases and emphasizes the need for controlled differentiation and further large-scale trials, but reports no new findings.

This study found that the phytosterols β-sitosterol, stigmasterol, and campesterol have low-to-negligible inhibitory activity against steroidal 5α-reductase type 2 compared to the synthetic inhibitor dutasteride, with β-sitosterol showing the highest activity among the tested phytosterols.

This study found that stabilizing β-catenin in a specific mouse model led to temporarily increased hair density but ultimately accelerated hair follicle aging and hair thinning.

This study found that disrupting Lm332 expression in mice changes keratinocyte genetic expression, alters cell shape, and disrupts epidermal homeostasis, despite some compensatory anchorage by hair follicle basal cells.
