This study found that a topical hedgehog agonist can stimulate hair growth by promoting the transition from the resting to growth phase of the hair cycle in adult mouse skin.

This article offers a viewpoint on hidradenitis suppurativa pathogenesis, suggesting that impaired Notch signalling from γ-secretase mutations may drive inflammation and link the condition to other Th17-driven diseases.

This study demonstrated that disrupting sonic hedgehog signaling, using cyclopamine, significantly impaired wound healing in a mouse model, suggesting its crucial role in postnatal tissue repair.

The researchers reported that mast cell and nerve fiber interactions in mouse skin are highly selective for nerve fiber types and vary depending on the hair cycle phase.

This paper discusses the cellular and molecular processes involved in root hair growth in higher plants, focusing on cytological phenomena and the effects of growth regulators and mutations, but reports no new experimental findings.

This review discusses advanced techniques for investigating stem cell fate at the single-cell level, including lineage tracing, time-lapse imaging, and molecular profiling, but reports no new research results.

This study found that PDGFA is critical for the proliferation and maintenance of adipocyte stem cells in skin but not other white adipose tissues, highlighting unique regulatory mechanisms in different tissue depots.

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

Lack of vitamin D receptor increases skin tumor risk by boosting hedgehog signaling.

This study found that the Wnt inhibitor Dkk4 may play a role in regulating hair follicle development through a feedback loop with canonical Wnt signaling pathways.

This study found that androgens inhibit hair follicle stem cell differentiation by disrupting the Wnt signalling pathway in dermal papilla cells, but Wnt activation can restore differentiation.

This study found that peripilar signs on the scalp are linked to perifollicular lymphocytic infiltrates in early androgenetic alopecia, detectable even in areas with high hair density.

This study found that transgenic mice overexpressing the BMP antagonist noggin showed increased hair follicle size and altered hair type, linked to changes in cell proliferation and gene expression.

CYP11A1 is crucial for skin health and disease by producing important steroids.

This study found that the E3 ligases NEDD4 and NEDD4L regulate intestinal stem cell priming by degrading the LGR5 receptor, and their loss leads to increased Wnt activation and crypt proliferation, which in turn accelerates intestinal tumor progression in mice.

This study found that Wnt signaling regulates the symmetric division of adult neural stem cells, increasing their numbers during subependymal regeneration, stroke response, and colony formation.

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

This article reviews advances in feather development and regeneration, including pattern formation, stem cell biology, and evolution, but presents no new experimental results.

This study found that epidermal Wnt production is crucial for forming the skin's spinous layer through a BMP-FGF signaling cascade, although Wnt from basal cells is not needed for their differentiation.

This study found that cellular retinoic acid-binding proteins and fatty acid-binding proteins are dynamically expressed in skin development and respond differently to retinoic acid, β-catenin, and Notch signaling.

This study found that epidermal growth factor significantly enhances the proliferation of hair follicle-derived mesenchymal stem cells through the EGFR/ERK and AKT pathways, without involving the STAT3 pathway.

This review explores embryonic epidermal development and discusses key molecular regulators and roles of the sub-epidermal mesenchyme, but reports no new experimental results.

This review examines PAK4 signaling pathways in prostate cancer, Parkinson's disease, and melanogenesis, focusing on the potential role of the PAK4-CREB axis, without reporting new clinical results.

This study conducted in situ tensile loading experiments with atomic force microscopy to observe how conditioning treatments affect the tensile response of virgin, chemically damaged, and mechanically damaged Caucasian hair.

This study found that both human and rat dermal papilla spheroids can induce hair follicle neogenesis, but larger spheroids increase inductivity without significantly affecting hair fiber diameter.

This study found that RSL4 in Arabidopsis thaliana regulates genes necessary for root hair elongation by controlling proteins involved in cell signaling, cell wall modification, and secretion.

This review discusses the adverse effects of 5α-reductase inhibitors, finasteride and dutasteride, on sexual, psychological, and vascular health, emphasizing the need for physicians to inform patients of these risks.
