Diphencyprone initially increases mouse hair growth, then slows it, possibly due to changes in specific protein levels.

This study demonstrates that keratin K2 is crucial for proper keratinocyte structure and function in specific mouse skin areas, and its deficiency leads to cellular aggregates and skin abnormalities.

In this study, synthetic vitamin D3 analogs stimulated hair growth and formation of normal hair follicles in nude mice, unlike the natural form 1,25 dihydroxyvitamin D3.

This study found that bulge cells marked by CD200+ in human hair follicles show high colony-forming efficiency, suggesting successful enrichment of keratinocyte stem cells.

This review discusses the development, lineages, functions, and roles of fibroblasts in fibrosis across four organs, highlighting their capabilities in tissue repair and contributions to fibrotic disorders when aberrantly activated, but it reports no new experimental findings.

This study systematically reviews the Wnt/β-catenin signaling pathway, discussing its origin, composition, function, involvement in tumors and diseases, and the development of small-molecular compounds targeting this pathway for disease treatment.

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 study reveals an antagonistic competition between BMP and Wnt signaling within stem cells, influencing their fate towards hair germ characteristics based on the BMP/Wnt activity ratio.

This review discusses the molecular mechanisms involved in hair follicle development and regeneration, highlighting findings from mouse genetic studies, and reports no new experimental results.

This study found that in mice, epidermal Wnt/β-catenin signaling influences adipocyte differentiation and hair growth, suggesting its critical role in synchronizing adipogenesis with the hair growth cycle.

This review discusses Wnt signaling pathways in skin development and stem cell regulation, highlighting potential interactions with other pathways but reports no new findings.

This study found that synchronized signals in the microenvironment regulate stem cell lineage choices in hair follicles by influencing chromatin dynamics during regeneration.

This study found that nestin-expressing cells in the hair follicle bulge exhibit multipotent stem cell-like properties and can generate neural cells both in vitro and in vivo.

This study found that inhibiting AP-1 activity in mice modified tumor development, leading to transdifferentiation between squamous and sebaceous tumors, with molecular analysis suggesting AP-1's role in maintaining tumor cell identity.

This study introduces a method for long-term expansion of adult mouse epidermal stem cells in vitro using an organoid culture system that maintains the basal-apical organization.

This study identified morphotype-specific gene expression patterns in feathers, enhancing understanding of the molecular and cellular processes involved in feather development and diversification.

This review examines the life cycle, biomarkers, and functions of hair follicle stem cells, emphasizing their role in hair loss therapy and other skin and hair disorders, but reports no new clinical results.

This study found that Wnt signaling, crucial for lung development, may be disrupted in severe asthma, potentially affecting cell proliferation and senescence through complex mechanisms.

This study found that large excisional wounds in rats across seven strains do not regenerate new hair follicles, unlike in mice, possibly due to differences in epidermal competence and transcriptional profiles.

This study found that zebrafish and sticklebacks, despite differences in their tooth regeneration structures, share a similar genetic program during tooth regeneration, suggesting a conserved "successional dental epithelium" in vertebrates.

This review discusses the pathogenesis of melasma, including genetic, environmental, and hormonal factors, and highlights potential avenues for new treatments and preventive strategies, but reports no new experimental findings.

This study revealed that BMP5 in onychofibroblasts may play a key role in the differentiation of nail matrix keratinocytes, highlighting transcriptional similarities between nail and hair structures.

This review suggests that telocytes in male reproductive organs help organize tissue structure and paracrine factors, impacting organ development and pathology, but more research is needed on their molecular pathways.

This study mapped gene expression in different skin structures of dogs, finding similarities to humans that support using dogs as models for human skin diseases.

This study shows that NIPP1 deficiency in mouse epidermis leads to hyperproliferation, hair loss, and chronic skin inflammation, which can be partially alleviated by dexamethasone treatment.

This review discusses recent findings on fibrotic lipodystrophy, highlighting the critical roles of lipid-filled cells in tissue function and their loss during fibrogenesis, with implications for fibrosis in tissues like skin, lung, and liver.

This review discusses selection signatures and selective sweeps in fiber-producing animals and recommends further genomic investigations to identify genes related to important fiber traits, without providing new results.
