This study found that androgen receptor activation in adult mouse skin reduces β-catenin-induced hair follicle growth and sebaceous gland conversion, highlighting its role in stem cell fate decisions.

This study demonstrated that FGF5s acts as an inhibitor of FGF5 in regulating hair growth cycles in cashmere goat dermal papilla cells.

This study reported that deleting the MED1 subunit from the MED complex in keratinocytes resulted in disrupted hair differentiation and cycling, leading to hair loss in mice.

This study explored the regenerative abilities of the African spiny mouse's skin, revealing more robust wound-induced hair follicle neogenesis compared to laboratory mice and highlighting unique features of its hair and wound response.

Understanding the hair growth cycle in mice is crucial for accurate research, as it affects study results and requires careful timing and methods.

This study found that overexpression of betacellulin in transgenic mice delayed hair follicle morphogenesis and cycling, increased keratinocyte proliferation, and enhanced wound angiogenesis without affecting wound healing strength.

This review discusses the role of stem cells in alopecia pathogenesis, highlighting the differences between scarring and nonscarring types, and reports no new clinical results.

This review discusses the therapeutic use of insulin-sensitizing agents in polycystic ovary syndrome, reporting improved ovulation, insulin sensitivity, and reduction of hyperandrogenism, but calls for larger studies to confirm these effects.

This study found that in adult mouse skin, reduced levels of histone H3 K4/K9/K27me3 during hair follicle stem cell quiescence are linked to proper tissue homeostasis.

This study found that placental growth factor (PlGF) enhanced hair shaft elongation and accelerated hair follicle growth, suggesting its potential as a therapeutic target for alopecia.

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.

In this study, inactivating the TAF4 subunit of transcription factor TFIID in mouse epidermis disrupted gene expression linked to skin and hair function, and increased tumor risk.

This study found that Undariopsis peterseniana extract may promote hair growth by activating specific cellular pathways, suggesting potential for treating alopecia.

This study found that HPV16 oncogene expression in multipotent epithelial stem cells led to abnormal mobilization, altering their quiescence without affecting other stem cell markers, suggesting a distinct stem cell compartment.

In this study, researchers found that coordinated intercellular Ca2+ signaling among basal stem cells in mice is crucial for cell cycle progression and tissue-wide communication during epidermal regeneration.

This study found that Foxp1, a transcriptional factor, plays a key role in regulating hair follicle stem cell proliferation by modulating oxidative stress and the cell cycle during hair growth phases.

This study found that deletion of c-Jun and JunB in mouse bulge hair follicle stem cells was sufficient to trigger psoriasis-like skin disease through thymic stromal lymphopoietin signaling.

This study identified distinct gene expression patterns in wool follicle bulbs that may play important roles in wool follicle cycling and regeneration in sheep.

This study found that in Pomeranians with Alopecia X, key genes in the Wnt and Shh signaling pathways and stem cell markers are downregulated, which may explain the absence of anagen hair follicles.

This study found that platelet-rich plasma may influence the proliferation of human hair dermal papilla cells by affecting gene expression related to the cell cycle.

This study found that ATM protein plays a crucial role in protecting human hair follicle melanocytes from oxidative stress, which is linked to the greying of hair.

In this study, vitamin D supplementation showed no significant effect on androgen levels or clinical hyperandrogenism in PCOS women, but when combined with metformin, it improved testosterone levels.

This study found that numerous genes involved in hair growth, including 73 co-up-regulated ones, were differentially expressed in goat hair follicles during the hair growth cycle.

This study found that transgenic mice overexpressing HGF/SF are more susceptible to UVA-induced melanoma, with melanin in the papillary dermis interacting with UVA to induce melanoma.

This study suggests that 3,4,5-tri-O-caffeoylquinic acid activates β-catenin to enhance pigmentation in mouse hair follicles, human melanocytes, and melanoma cells during the hair cycle's growth phase.

This review discusses the histologic features of nonscarring alopecia and highlights the importance of clinical-pathological correlation for accurate diagnosis, but reports no new clinical results.

This study found that exosomes from hair follicle mesenchymal stem cells overexpressing lncRNA H19 promoted diabetic skin wound healing by enhancing cell proliferation, migration, and reducing pyroptosis.
