This study found that phosphatidic acid promotes hair growth by stimulating cell proliferation and protecting against apoptosis in murine hair epithelial cells, unlike lysophosphatidic acid, which showed limited effects.

This study reported that disrupting ephrin-Eph interactions in adult mouse skin doubled cell proliferation in the hair follicle and epidermis, suggesting ephrins as negative regulators of proliferation.

In this study, transgenic male mice over-expressing the androgen receptor in mesenchymal stem cells showed reduced fat mass and improved glucose clearance, suggesting enhanced androgen sensitivity may alter body composition.

This study found that human outer root sheath cells express VEGF receptor-2, and exogenous VEGF165 significantly stimulates their proliferation through activation of the ERK signaling pathway.

This study found that human umbilical cord blood mesenchymal stem cells promoted hair growth by advancing anagen onset and increasing hair follicle regeneration in an in vivo model.

This review discusses various approaches to treating alopecia, including drug therapy and hair transplantation, but reports no new research findings; the authors highlight the need for novel techniques like cell culturing.

This study found that 1,25 dihydroxyvitamin D3 significantly increased the expression and activity of vasculoprotective natriuretic peptide receptor-A in cultured inner medullary collecting duct cells, suggesting a potential mechanistic role in cardiovascular and renal benefits.

This study found that finasteride effectively prevented testosterone-induced kidney stone formation in renal tubular cells by reducing COM crystal adhesion and crystallization.

This study concluded that early-stage tissue-engineered skin substitutes, developed using skin progenitor cells, had a better graft efficiency and supported hair follicle formation, which may improve wound healing outcomes.

This study found that glioblastoma cells express key enzymes involved in androgen synthesis, suggesting these enzymes might be potential targets for new therapeutic strategies.

This study found that topical application of metformin significantly enhanced skin regeneration in mechanically stretched skin in rats, likely by boosting the proliferation of skin-derived stem cells.

This review discusses the insights gained from single-cell RNA sequencing of fibroblasts in various cancers and wound healing, highlighting differences in gene expression and novel interactions.

This study used cashmere goats to reveal distinct intermediate states of dermal papilla cells, each with specific roles in hair growth, shedding, and regeneration.

This case report describes a 69-year-old woman with hirsutism and elevated serum testosterone, where surgery resolved symptoms and serum testosterone, suggesting ovarian steroid cell tumor consideration in similar profiles.

This study identified specific markers that can distinguish between stem cells in different regions of human scalp hair follicles, offering potential strategies for cell sorting and purification based on these markers.

This study found that specific human hair keratins are differentially expressed in the hair follicle, suggesting a shared pathway of epithelial differentiation between hair cortex and nail plate cells.

This study observed that autologous bone marrow derived mononuclear cells and follicular stem cells were both safe and effective for improving resistant alopecia areata and androgenetic alopecia, with no serious adverse events.

This review discusses immunohistological and immunofluorescent methods for studying the human hair follicle cell cycle, reporting no new results, and suggests its potential for advancing cell cycle research.

This case report highlights a rare instance of postmenopausal virilization in a 71-year-old woman due to coexisting ovarian hilus cell hyperplasia and a Sertoli-Leydig cell tumor.

This study shows that macrophage-induced TNF signaling can activate hair follicle stem cells and promote new hair follicle formation after wounding by regulating AKT/β-catenin pathways.

This study explored the interaction between androgen and Wnt signaling in dermal papilla cells, targeting the effects of androgen on hair growth reduction.

This study found that LED light irradiation induced proliferation and migration of human outer root sheath cells, potentially through the stimulation of the Wnt/β-catenin and ERK signaling pathways.

This study found that loss of the Pten gene in Lgr5+ hair follicle stem cells promoted squamous cell carcinoma formation through the Akt/β-catenin signaling pathway.

This study suggests that mesenchymal stem cell therapy may improve cell viability and regulate key signaling pathways in vitro for treating alopecia areata.

This study found that upregulation of NFIC may enhance proliferation and osteogenic/cementogenic differentiation in rat dental follicle cells.

This study found that the interaction between heat shock protein 90 and lamin A/C is crucial for the growth, migration, and self-aggregation of dermal papilla cells, suggesting a potential role in alopecia areata mechanisms.

This study found that stress hormones, particularly CRF, can inhibit hair growth and induce hair loss by affecting human dermal papilla cells and hair follicles, suggesting a functional HPA axis in these cells.

This study observed that the OCIAD2 and DCN genes in Liaoning cashmere goats have opposite effects on hair growth by interacting with the TGF-β signaling pathway, influencing follicle morphogenesis and periodic changes.

TR3 is mainly found in hair follicle stem cells and may be involved in hair loss.

This case study describes a 15-year-old girl with a Sertoli–Leydig cell tumor who showed high androgen levels and steroidogenic responses similar to patients with polycystic ovary syndrome before surgery.
