This review discusses the role of TGF-β signaling in stem cell recruitment and tissue regeneration, indicating that abnormalities in TGF-β activation contribute to various major diseases and suggesting avenues for therapeutic intervention.

This study demonstrated that blocking the Sonic hedgehog signaling pathway in mice led to reversible inhibition of body coat hair morphogenesis, while whisker development was unaffected.

This review discusses skin-related toxicities associated with targeted cancer therapies and emphasizes the need for dermatologists to understand and manage these adverse effects, but reports no new experimental results.

This review discusses the conserved molecular mechanisms controlling hair follicle development and cycling and suggests they may also apply to other ectodermal derivatives, like teeth and feathers, but it reports no new results.

This review covers recent findings on stem cell plasticity under normal and cancerous conditions but presents no new experimental results, highlighting implications for regenerative medicine and cancer treatments.

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 overexpression of miR-214 in keratinocytes inhibits hair follicle development and cycling by targeting β-catenin in the Wnt signaling pathway.

This study found that laminin-511 is crucial for hair morphogenesis in mice, as it influences primary cilia formation and dermal papilla maintenance through noggin and sonic hedgehog signaling.

This study identified WNT10A as crucial for adult epithelial cell proliferation and differentiation, suggesting β-catenin pathway activation may help address regenerative defects in WNT10A mutation patients.

This study found that sympathetic nerves and arrector pili muscles form a niche that modulates hair follicle stem cell activity, revealing their role in hair follicle regeneration.

This review discusses recent findings on hair follicle morphogenesis and regeneration, focusing on molecular signals and stem cells, and suggests that understanding these processes may aid in developing new strategies for wound healing.

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 identified five mutations in the gene LSS in individuals with unexplained hypotrichosis simplex, highlighting a potential role of mislocalized LSS proteins in disrupting hair follicle biology.

Finasteride increases hair density in female androgenetic alopecia, but individual results may vary.

This study observed that patients with CYLD mutations frequently experienced severe, painful tumors beyond the head and neck, impacting their quality of life, with hormonal factors possibly contributing to tumor development.

This article discusses the role of growth hormone, insulin, and IGF-1 in acne development and highlights how diet and syndromic evidence support their involvement, but presents no new clinical findings.
