This study reported that stress can induce hair graying in mice through noradrenaline-mediated depletion of melanocyte stem cells in hair follicles, providing a mechanism that connects stress to hair color changes.

This study found that neonatal Regulatory T cells are crucial for maintaining PPARγ signaling in hair follicles, which supports melanocyte stem cell function and skin pigmentation during early postnatal development.

This review discusses the regulation and dynamics of the Wnt/β-catenin signaling pathway in development, pluripotency, and cancer, highlighting potential mechanisms and future research directions, but reports no new results.

This review covers recent developments in materials for in vitro and in vivo stem cell manipulation, highlighting innovative substrate properties but does not report new experimental results.

This study found that melatonin may enhance goat cashmere growth by activating Wnt signaling and regulating stem cell pluripotency through mechanisms involving NOGGIN and BMP4 pathways.
