This review examines the roles of Smad-4 and Smad-7 in hair follicle differentiation and development through BMP signaling and TGFβ/Activin/BMP pathway inhibition but reports no new experimental results.

This review discusses emerging treatments and mechanisms for alopecia, highlighting potential therapies like janus kinase inhibitors and advances in stem-cell technology, but reports no new experimental results.

This genome-wide association study identified 20 genetic signals at 15 risk loci related to severe acne, revealing new insights into its genetic predisposition, particularly affecting skin structure and maintenance.

This study found that Eda and activin A regulate Foxi3 expression, which may contribute to the development of hypohidrotic ectodermal dysplasia by affecting Foxi3 activity in ectodermal appendages like hair and teeth.

This review explores the potential (neuro-)endocrine influences on hair follicle epithelial stem cell biology and emphasizes the need for more systematic research, but it provides no new empirical results.

This study found that reducing BMP signaling in mouse nipple epithelia, achieved through Noggin overexpression, can convert them into hairy skin with pilosebaceous units.

This review synthesizes recent findings on the hair follicle stem cell niche and its complex interactions, exploring potential pathways for developing new hair growth therapies; it reports no new clinical results.

This study suggests that canonical BMP signaling, particularly involving Smad1 and Smad5, plays a critical role in hair follicle stem cell regulation and hair morphogenesis, with distinct roles from pSmad8.

This study found that the loss of Smad4 in keratinocytes reduces Dsg4 expression via disrupted BMP signaling, contributing to hair follicle degeneration and alopecia.

In this review, the authors discuss how understanding and co-regulating multiple signaling pathways could lead to effective regeneration of functional hair cells, highlighting current achievements and future approaches such as small molecule drugs and gene therapy for treating sensorineural hearing loss.

This study found that in wound-induced hair neogenesis, African spiny mice and laboratory mice exhibit different morphogenetic field formation patterns related to tissue stiffness, suggesting evolutionary developmental biology advantages.

The document concludes that there are still unknowns about the effectiveness, risks, and detection of performance-enhancing drugs, and doping remains a challenge.

This study found that maternal sub-maintenance nutrition reduced the density and branching ratio of secondary wool follicles in Merino sheep fetuses and identified genes potentially involved in these processes.

This study found that 5% primed conditioned medium from human umbilical cord blood-derived mesenchymal stromal cells significantly improved hair density, thickness, and growth rate in patients with androgenetic alopecia.

This review discusses emerging targets for developing drugs to treat hair loss and reports no new clinical results; the authors emphasize the potential for therapies that regenerate hair follicles.

This study reports that dynamic interactions between stem cells and their niche, influenced by macro-environmental factors, regulate regenerative behavior in integument pattern formation.

This study identified 77 genes with significant expression changes in expanded human skin, suggesting possible mechanisms for skin regeneration during tissue expansion, including previously unreported genes like HOXA5, HOXB2, and AP1.

This study suggests that human embryonic stem cells may improve skin graft quality and functionality by enabling the identification and amplification of early ectodermal progenitors, pending confirmation from preclinical studies.

Gene therapy shows promise for enhancing physical traits but faces ethical, safety, and regulatory challenges.

This study reported that exogenous R-spondin-1 can restore hair follicle neogenesis in adult mouse cells, highlighting differences in gene expression and signaling pathways between fetal and adult dermal papilla cells.

This study found that bulge-derived keratinocytes from human follicles were more resistant to differentiation compared to epidermal keratinocytes, possibly due to WIF-1 involvement.

This study observed that downregulation of laminin-511 plays an important role in hair regression during the catagen stage in mice.
