This article reviews the complex signaling pathways between epithelial and mesenchymal cells crucial for hair follicle morphogenesis, highlighting the Wnt pathway's role as a master regulator without reporting new experimental findings.

This study found that micro-niches within hair follicles create heterogeneity among stem cells and transit-amplifying cells, leading to specialized progenitors that control tissue morphogenesis and regeneration.

This review discusses the niches supporting adult stem cells in various organisms, including well-studied germline niches and the less understood mammalian niches, but it reports no new research findings.

This study found that loss of Apc due to K14-cre-mediated gene recombination in mice led to aberrant growth in ectodermally derived squamous epithelia, implicating its critical role in specifying epithelial cell fates during embryonic development.

This review summarizes current knowledge on tight junctions in mammalian skin and their role in drug delivery and interaction with other barrier components, but reports no new experimental results.

This study found that cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.

This review discusses the extraction, purification, modification, and biological activity of polysaccharides from Traditional Chinese Medicine and reports no new research findings.

This study demonstrated that stress inhibited hair growth in mice, likely through substance P-dependent activation of immune cells, highlighting a brain-hair follicle connection.

This study reports that miR-302 promotes pluripotency by inhibiting NR2F2 and indirectly regulating OCT4 in stem cells, enhancing reprogramming efficiency when added to traditional factors.

This study found that K17 is crucial for the structural integrity and survival of hair-producing cells, with K17 null mice developing alopecia due to hair fragility and follicular alterations.

Minoxidil can help grow hair in mice by making cells grow and improving hair quality. More research needed.
