This study found that a hypoxic microenvironment enhanced the proliferation and pluripotency of adipose mesenchymal stem cells, promoting hair follicle formation and upregulating specific growth factors in Arbas Cashmere goats.

This study found that human dermal stem/progenitor cells demonstrated greater proliferation and differentiation potential than hair follicle dermal papilla cells, which showed increased expression of hair regeneration markers.

This study found that minoxidil stimulates hair follicle growth by promoting dermal papilla cell survival and activating ERK and Akt pathways, which leads to increased proliferation and reduced cell death.

This study suggests that LED light may promote the proliferation of human dermal papilla cells through the activation of specific signaling pathways.

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.

This study found that synthetic melanin particles applied topically in mouse injury models improved wound healing, showing potential as a therapy for accelerated healing, including in human skin explants.

This study suggests that Houttuynia cordata extract may promote hair growth by stimulating dermal papilla cell proliferation and extending the anagen phase through enhanced energy metabolism and gene expression changes.

In this study, minoxidil and human platelet lysate affected gene expression related to hair growth signaling pathways in mouse hair follicle cells.

This study found that myristoleic acid promotes dermal papilla cell proliferation and anagen signaling through autophagy, cell cycle progression, and activation of the Wnt/β-catenin and ERK pathways.

This study found that upregulated miR-149 restricted hair follicle stem cell differentiation and hair growth by inhibiting the MAPK1/ERK2 pathway, which affects FGF2 and c-MYC expression.

This study found that compounds isolated from Osmanthus fragrans var. aurantiacus demonstrated antioxidative and anti-inflammatory activities, potentially offering therapeutic benefits for inflammatory bowel diseases by inhibiting COX-2 and iNOS enzymes and blocking ERK 1/2 MAPK signaling.

Mycophenolic acid may help hair grow by activating pathways important for hair growth.

Mycophenolic acid may help hair growth, a combination treatment improves hair thickness in male hair loss, and early treatment of frontal fibrosing alopecia is important.

This review discusses the adverse skin effects of EGFR inhibitors used in cancer treatment, exploring their mechanisms and offering strategies for prevention and management, but reports no new experimental findings.

This report suggests that TCDD may alter human epidermal stem cell populations by upregulating c-Myc, potentially leading to increased stem cell turnover during chloracne development.

This review compiles current knowledge of Eclipta prostrata's botanical details, ethnomedical uses, phytochemical components, and various pharmacological activities, emphasizing its potential for modern pharmaceutical formulations based on its anti-inflammatory, antioxidant, anticancer, and other therapeutic properties.

This study found that salivary testosterone concentrations correlated better with hirsutism in women compared to serum testosterone measures, suggesting it may be an effective method for assessing bioavailable testosterone.

This study found that spironolactone reduced hirsutism scores in women without significant hormonal changes, suggesting its effectiveness primarily through peripheral mechanisms.

In a mouse model, this study found that exposure to PM2.5 leads to significant postpartum hair loss, apparent via morphological changes and elevated markers of inflammation, apoptosis, and fibrosis, potentially exacerbated by changes in hormone receptors and stem cell populations.

In this study, minoxidil significantly downregulated interleukin-1 alpha expression in human keratinocyte cells, suggesting an anti-inflammatory effect that may be a mechanism of action in treating alopecia.

This study found that S-Methylmethionine sulfonium (SMMS) enhances cell survival and reduces damage from UVB irradiation in skin cells, suggesting its potential as a cosmetic ingredient for UV protection.

In this study, a peptide hydrogel scaffold loaded with umbilical cord-derived mesenchymal stem cells was used to repair damaged endometrium in rats, significantly improving fertility and live birth rates by restoring endometrial thickness and promoting angiogenesis.

This study observed that minoxidil significantly downregulated 5α-R2 gene expression in human keratinocyte cells, suggesting an antiandrogenic mechanism of action in alopecia.

In this study, knockout of B-raf and C-raf genes in mice showed they are not needed for early melanocyte development, but are crucial for maintaining melanocyte stem cells, as evidenced by hair graying due to stem cell depletion.

This study found that thymosin beta-4 overexpression in mice increased hair growth speed and density, likely by regulating P38/ERK/AKT signaling through VEGF expression.

This study found that transgenic mice expressing cgVEGF164 had increased hair follicle diameter and density, potentially linked to higher phosphorylation levels of ERK1/2, AKT1, and LEF1 proteins.

This study explored the effects of DPP, a 15-PGDH inhibitor, on human follicle dermal papilla cells damaged by dihydrotestosterone and observed that DPP enhanced wound healing, reduced reactive oxygen species, and increased hair growth in ex vivo human hair follicle cultures.

This review discusses the regulation of involucrin gene expression, focusing on transcription factors and signaling pathways, and reports no new experimental findings.

In this study, polydopamine emerged as a safe and effective alternative to traditional hair dyes like PPD for dyeing gray hair permanently, showing resistance to detergents and causing less toxicity and hair loss in mice.

This study observed a microbial shift on the scalp of Alopecia areata patients, characterized by an increase in Propionibacterium acnes and a decrease in Staphylococcus epidermidis, compared to healthy controls.
