This study found that skin-resident Treg cells regulate hair follicle stem cell proliferation and differentiation through the Jag1-Notch signaling pathway, influencing hair regeneration.

This study demonstrates that FMOD deficiency in mice alters TGF-β ligand and receptor expression during wound healing stages, leading to delayed wound closure and increased scar size.

This study found that sebaceous glands in the skin are primarily renewed by their own stem cells during normal conditions, but after injury, they regenerate through stem cells from hair follicles, highlighting stem cell plasticity and regeneration capabilities.

This study found that human skin melanocytes with low mutation burdens are smaller, less dendritic, and exhibit stem-like features, often residing in UV-protected hair follicles, suggesting their role in replenishing sun-damaged epidermis.

This review discusses the identification and roles of different epidermal stem cell types in skin homeostasis and repair, and reports no new experimental findings.

This study found that rhamnose can restore hair-inducing gene expression in dermal papilla cells and accelerate hair follicle regeneration by promoting the hair cycle into the anagen phase, suggesting its potential therapeutic application for alopecia treatment.

This study found that in Liaoning cashmere goats, overexpression of the PIP5K1A gene enhances skin fibroblast proliferation, while interference with this gene reverses melatonin-induced proliferation, and PIP5K1A regulates certain miRNA expressions, suggesting a role in improving cashmere yield and quality.

This study suggests that skin-derived precursors from Sox2(+) hair follicle dermal cells have the potential to function as dermal stem cells, supporting hair morphogenesis, dermal maintenance, and wound-healing.

This study suggests that ethylene and lignoceric acid (C24:0) may promote cotton fiber and Arabidopsis root hair growth by activating the pectin biosynthesis network.

In this study, researchers observed that a noncanonical mechanism involving the γ-secretase-dependent, RBPj-independent Notch intracellular domain improves survival in Msx2-Cre mice by delaying hair follicle destruction and reducing disease severity.

In this study, a mixture of tocopherol acetate, L-menthol, and stevioside was more effective in promoting hair growth in mice compared to tocopherol acetate or L-menthol alone.

This study found that transplanting hair follicles into human scars may remodel fibrotic tissue and reduce scarring by altering collagen structure and decreasing pro-fibrotic factors.

This review discusses the evaluation of hyperandrogenemia in women and hypogonadism in men across different life stages and presents biomarkers used for diagnosing male hypogonadism, reporting no new clinical results.

This study found that aging mice experience slower and more fragmented hair cycle waves, but transplanting aged skin to a young host can partially restore hair cycling, implicating extracellular factors.

This study found that ectopic expression of Whn in transgenic mice caused impaired differentiation in epidermis and hair follicles, with hair growth defects and severe urinary tract issues leading to hydronephrosis.

This study found that overexpression of Wnt1a in bone marrow mesenchymal stem cells enhanced mouse hair follicle regeneration and promoted hair cycling.

This study found that testosterone enhances insulin secretion in human pancreatic islets by being converted into DHT and E2, processes that are necessary for this effect.

This study found that by using an automated system to analyze skin histology, 108 structural features were significantly affected by age, and it identified four new aging biomarkers and notable sex-based differences in skin aging.

This study demonstrated that CD19-CAR T cell therapy may promote structural regeneration in the skin of systemic sclerosis patients, as evidenced by histological improvements and fibroblast population changes, suggesting its potential for tissue remodeling in fibrotic diseases.

This review discusses hair follicle organoids as emerging models for studying hair biology and disorders, emphasizing their promise for bridging basic research and clinical applications, but reports no new results.

This study found that arrector pili muscles formed by Sonic Hedgehog signaling play a critical role in maintaining sympathetic nerve connections to hair follicle stem cells, influencing hair regeneration, with implications for hair loss treatments.

This study found that Ca²⁺ signaling and peptidylarginine deiminase enzymes play a crucial role in activating neural stem cells in response to injury in zebrafish, suggesting potential therapeutic targets for CNS injuries and cancer.

This study found that mechanical skin stretching can stimulate hair stem cell proliferation and hair regeneration by activating a complex pathway involving WNT, BMP-2, and M2 macrophages.

This study found that hair follicle patterning in development may arise from a combination of epidermal prepattern signals and mesenchymal self-organisation, with fibroblast growth factor and bone morphogenetic protein activities playing key roles.

This essay discusses the establishment, maintenance, and role of skin stem cells in tissue homeostasis, wound repair, and their relation to skin cancer, without reporting new experimental findings.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

This review discusses current experimental approaches for regenerating human hair follicles using tissue engineering and isolated cells, but reports no successful strategies with adult cells yet found.

This study found that activation of Wnt/β-catenin signaling in mouse testes promotes spermatogonial differentiation and reduces the stem cell pool, with SHISA6 inhibiting this process and maintaining stem cell characteristics.

This review discusses circadian clock regulation in stem cells and its role in processes like neurogenesis, but reports no new results; the authors emphasize its significance in stem cell function across various tissues.

This study found that Sonic Hedgehog secreted by hair follicle transit-amplifying cells is essential for dermal adipogenesis and hair follicle growth by acting on adipocyte precursors.
