This study found that in mice, low-dose irradiation causes stem cells in hair follicles to undergo chromatin alterations, which may eventually lead to long-term functional loss in tissues or organs.

In this study, ethyl acetate fraction of Eclipta alba was found to inhibit adipogenesis and reduce dyslipidemia in hamsters, suggesting potential as an herbal treatment for obesity.

In this study, topical application of Hominis Placenta significantly promoted hair regrowth and increased hair density in C57BL/6 mice, suggesting its potential as a treatment for alopecia.

This study found that early passage dermal papilla cell-derived extracellular vesicles, combined with specialized medium, helped adipose-derived stem cells develop dermal papilla-like properties.

This study found that stem cells from human deciduous teeth promoted hair regeneration and increased hair formation in mice, suggesting a potential mechanism involving the Shh/Gli1 pathway.

This study found that a new hydrogel formulation of basic fibroblast growth factor showed promise in promoting hair regrowth and reducing inflammation in testosterone-treated mice.

This study suggests that Platycarya strobilacea extract promotes hair growth in mice by enhancing stem cell factor expression, reducing mast cell numbers, and increasing cytokines associated with hair growth.

This study found that octahydrobenzo[c]quinolizin-3-one derivatives, particularly compound 3, were potent and selective inhibitors of the enzyme 5α-reductase type 1.

In this study, hUCMSCs-Exo significantly accelerated wound healing in rat perianal fistulas with notable safety, potentially through the activation of the HIF-1α/TGF-β/Smad signaling pathway.

This review discusses sex differences in immune response to respiratory viral infections, including SARS-CoV-2, and highlights that hormones like estrogen may provide females with better protection, but it reports no new results.

This study found that an extract from the root of Sophora flavescens Aiton significantly improved hair growth in patients with androgenetic alopecia over 6 months.

This review discusses the history and challenges of hair follicle regeneration using follicular fragments and dissociated cells, without presenting new clinical results.

This study reports that melanocytes form a defined photoresponsive network in the skin that reads environmental light cycles and may influence the sleep-waking cycle similar to the pineal gland.

This study demonstrates that Rac1 activity is essential for normal hair follicle formation but influences hair structure and pigmentation, in terminal differentiation, through alterations in hair shaft, cuticle, and pigmentation organization.

In this study, researchers identified a novel homozygous variant in the FAM83G gene responsible for autosomal recessively inherited palmoplantar keratoderma with curly hair in a consanguineous Pakistani family, suggesting FAM83G plays a crucial role in skin and hair homeostasis.

In this study, overexpression of secretory phospholipase A2 Group-IIA in transgenic mice led to depletion of hair follicle stem cells and increased differentiation, linked to changes in histone modifications.

This study observed that amino acid uptake into wool follicles varies significantly, with cysteine showing the highest uptake rate, suggesting specialized transport systems that may influence wool growth.

This study found that injecting keratin into the skin of mice promoted hair growth, potentially through keratin's interaction with hair-forming cells and changes in the microenvironment.

In this study, researchers demonstrated that human hair keratins can self-assemble into stable nanofibrous networks in vitro, which are compatible with human skin cells and useful for regenerative applications.

The document concludes that early diagnosis and treatment are crucial for managing skin diseases in ferrets.

This study identified molecular elements controlling the expression and stabilization of THH protein in hair follicle cells, revealing key mechanisms that support hair shaft development in mice.

This study reports that two mouse models of scarring alopecia exhibit similar patterns of hair loss progression despite histological differences in inflammatory cell localization and MHC class I expression.

In this study, Epimedii Folium extract was found to enhance melanin production and promote pigmentation through mechanisms involving the MAPK/ERK1/2 pathway in both in vitro and in vivo models.

This study found that human mesenchymal stem cell-derived extracellular vesicles promote the proliferation and migration of hair follicle cells and increase hair shaft elongation in cultured human hair follicles.

This study suggests that CGE may enhance hair growth by activating β-catenin signaling pathways in human hair dermal papilla cells and promoting the anagen growth phase in mice.

This study observed that exosomes from adipose-derived stem cells promoted hair growth by enhancing dermal papilla cell proliferation and activating signaling pathways, suggesting potential for treating immune-mediated alopecia.

Caffeine can damage hearing cells and affect hearing recovery after ear trauma.

This study found that fibroblast-engineered nanovesicles significantly enhanced proliferation and migration of dermal papilla cells and increased hair follicle shaft size in ex vivo organ cultures, suggesting potential as a treatment for alopecia.

This study found that pelage abnormalities in Harlequin mutant mice are linked to severe AIF deficiency and associated with altered expression of genes related to hair structure.
