This review identifies genetic mutations associated with congenital hair loss disorders in Japanese populations, particularly highlighting common LIPH gene mutations linked to woolly hair/hypotrichosis, and reports no new clinical results.

This study used single-cell RNA sequencing to create a detailed atlas of human scalp hair follicles and found that early-stage hair graying involves matrix hair progenitor depletion linked to P53 pathway activation.

This review discusses the challenges in identifying specific hair follicle antigens involved in initiating alopecia areata and highlights the need for further research to understand its etiopathogenesis, reporting no new results.

In this study, researchers observed significant morphological and histological differences in transplanted hair follicles compared to native donor follicles post-FUE hair transplantation for androgenetic alopecia, highlighting substantial variations in sebaceous gland and root sheath degeneration at the recipient site.

This study used a novel fluorescent tagging method in mice to observe collagen IV dynamics during hair follicle development, revealing that alterations in basement membrane turnover can influence epithelial progenitor cell behavior and organ morphology by affecting cell proliferation and movement.

This article provides an in-depth exploration of both natural and synthetic treatments for alopecia, examining their mechanisms, benefits, limitations, and current research, while noting that synthetic therapies can have potential adverse effects.

This review summarizes how genetic studies using conditional β-catenin loss- and gain-of-function mice have advanced understanding of canonical Wnt signaling's role in embryonic development, adult stem cell maintenance, and cancer modeling.

This study found that CRISPR/Cas9-mediated disruption of the FGF5 gene in goats increased hair follicle numbers and fiber length, suggesting more cashmere production could be achieved.

This study found that SARS-CoV-2 hijacks the host factor IGF2BP1 to stabilize its RNA and enhance translation, and identified Cepharanthine and Trifluoperazine as potential treatments against the virus.

This study identified genomic regions and candidate genes that may contribute to phenotypic diversity in coat color, body size, cashmere traits, and high-altitude adaptation in domesticated goat breeds.

This review discusses the role of Wnt/β‐catenin signaling in stem and cancer stem cell maintenance and its involvement in the development and regeneration of various organs, but reports no new experimental results.

This study suggests that a position effect disrupting TRPS1 expression may be linked to hypertrichosis in both Ambras syndrome in humans and a similar phenotype in Koa mice.

This review examines the evolving understanding of lymphatic vessel development, emphasizing new cellular mechanisms and lineage diversity, while discussing experimental methods and identifying key knowledge gaps.

The study found that exposing Arbas Cashmere goats to a short photoperiod significantly increased cashmere production by extending the anagen phase of hair follicles, with gene expression changes identified as contributing factors.

This study sequenced and analyzed the goat skin transcriptome, revealing genes involved in signal transduction and cell communication that are differentially expressed during hair growth phases, providing insights for Cashmere goat breeding.

This study reports that miR-22 promotes cancer progression and metastasis by maintaining Wnt/β-catenin signaling and cancer stem cell function.

This study found that arctiin, a compound from Arctium lappa, demonstrated protective effects against oxidative stress-induced dysfunction in human hair dermal papilla cells, suggesting potential therapeutic use for alopecia.

This study suggests that controlling light exposure can influence cashmere growth by triggering hair follicles to enter their active growth phase sooner, potentially involving the CSDC2 gene as a key regulator.

This study found that colchicine treatment significantly reduced hair fiber elongation in cultured hair follicles and altered protein expression and activity in dermal papilla cells, suggesting a role for the ubiquitin-proteasome system in its effects.

In this study, researchers reported that CD34 expression in the isthmic region of canine hair follicles suggests a potential stem cell compartment in this area.

Dermoscopy is a good, noninvasive way to see normal cat skin structures and could be useful for check-ups.

This study found that telomere shortening disrupts BMP/pSmad/P63 signaling, leading to skin atrophy via Follistatin up-regulation, and suggests potential therapeutic targets.
