In this study, epidermal Notch activation increased jagged 1 expression, leading to skin changes like thickening and blistering, with these effects inhibited when jagged 1 was absent.

This study found that STAT5 activation in the dermal papilla acts as a key switch to trigger anagen entry in postdevelopmental hair follicle cycling.

This study found that reducing HDAC1 activity in the skin of mice led to defects in hair follicle structure and pigmentation, highlighting HDAC's role in skin and hair maintenance.

This study found that the PI3K-Akt signaling pathway is essential for regenerating new hair follicles when epidermal stem cells and skin-derived precursors are combined, suggesting potential therapeutic applications for hair regeneration.

This study found that chitosan and surface-deacetylated chitin nanofibrils promoted hair growth in mice and increased fibroblast growth factor-7 production in human follicle dermal papilla cells.

This article reviews the clinical and histological features of acanthosis nigricans and its associations with insulin resistance and other conditions, but highlights the need for more research on its classification, severity assessment, and treatment options.

This review discusses the role of the immune niche in hair follicle regeneration and its impact on different forms of alopecia, highlighting research gaps and potential therapeutic strategies.

Acne is significantly influenced by genetics, and understanding its genetic basis could lead to better, targeted treatments.

This study found that arachidonic acid may promote hair growth by enhancing dermal papilla cell function and stimulating the anagen phase in C57BL/6 mice.

This study suggests that inactivation of β-catenin is necessary for chick retina regeneration, as it allows cells to enter the cell cycle during injury and promotes regeneration without needing FGF2.

This review discusses methods for evaluating hair growth-promoting effects of candidate substances for androgenetic alopecia, focusing on cell assays, organ cultures, and animal models, and reports no new results.

This study found statistically significant patterns in hair morphology and ultrastructure linked to biogeographic ancestry among European, African, and East Asian populations.

This study observed that in wild snowshoe hares, gene expression patterns during seasonal coat color change show a consistent lag between gene expression and visible coat color changes.

In this study, the researchers found that vitamin D and calcium signaling in keratinocytes are essential for normal skin regeneration after wounding, with deficiencies significantly delaying wound closure and re-epithelialization in mice.

This review introduces an integrated view of hair follicle behavior, highlighting a Yin Yang model of regulation and suggesting glycans as key elements in hair follicle growth control, without reporting new clinical findings.

In this study, adenosine was found to stimulate hair follicle growth in vitro by promoting growth factor expression, β-catenin activation, and downstream signaling pathways.

In this study using genetic mouse models, researchers discovered that senescent melanocytes in nevi secrete osteopontin, which activates hair stem cells, enhancing hair growth; this process is mirrored in human hairy nevi, suggesting a potential therapeutic target for regenerative disorders.

This study suggests that Thyroxine (T4) may promote key features of human skin wound healing, such as re-epithelialization and angiogenesis, in an ex vivo model.

In this study, topical tofacitinib significantly increased hair regrowth in mice compared to minoxidil or vehicle, potentially due to elevated VEGF levels and reduced inflammation.

This article reviews the role of microRNAs as epigenetic modulators in dermatology but reports no new clinical findings.

In this study, a topical formulation with compounds from the monoterpenoid family significantly improved hair growth indicators like anagen:telogen ratio, hair fall, and visual hair density in men and women with pattern hair loss.

This study found that skin disorders are prevalent among elderly individuals and are often associated with underlying systemic diseases.

This review highlights similarities in the development of thymus and skin epidermis, reporting no new results; the authors emphasize shared molecular mechanisms despite different embryonic origins.

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 PBX1 enhances the proliferation and reprogramming of hair follicle mesenchymal stem cells by activating the AKT/GSK3β signaling pathway, promoting NANOG expression, and inhibiting apoptosis.

This review explores regenerative medicine approaches for vitiligo and alopecia areata, focusing on pathways for repopulating melanocytes and regrowing hair follicles, and summarizes potential treatments without reporting new clinical results.

This study found that tannic acid accelerated wound healing in rats by modulating inflammatory cytokines, increasing growth factors, and activating the Erk 1/2 pathway.

This review outlines dermatological toxicities associated with targeted cancer therapies and immunotherapies, emphasizing the need for collaborative management by oncologists and dermatologists but reports no new clinical findings.

This study found that phenyl-imidazole sulfonamide derivatives, particularly ISCK03, inhibited c-kit signaling and promoted depigmentation in various experimental settings, suggesting potential use as skin-whitening agents.

In this study, quercitrin was reported to promote hair growth and cell viability in cultured human dermal papilla cells by enhancing cellular energy metabolism and growth factor production via MAPK/CREB signaling.
