HGF activator helps convert HGF to its active form, promoting hair growth.

This review discusses the use of Tisseel for stabilizing particulate grafts and reports no new clinical results; the authors emphasize the need for further controlled trials.

Ets2 gene is crucial for placental development in mice.

In this study, androgen did not affect keratinocyte growth in coculture with androgenetic alopecia-derived dermal papilla cells, but did significantly suppress keratinocyte growth when androgen receptor was overexpressed in the papilla cells.

This study found that Smad7 perturbs hair follicle development while promoting sebaceous gland formation by antagonizing Wnt/β-catenin signaling in transgenic mice.

This study found that cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.

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 review suggests that understanding the biological and molecular reasons for more severe COVID-19 in men, particularly those at risk for prostate cancer, could improve management of these patients, but reports no new results.

This study found that EGCG from green tea may stimulate human hair growth by promoting the proliferation and anti-apoptotic activity in dermal papilla cells.

In this study, sequences upstream of the TGM3 gene were found to regulate epithelial-specific gene expression in keratinocytes, suggesting potential applications in gene therapy.

This study found that activin affects both stromal cells and keratinocytes in skin morphogenesis and repair, with dose-dependent effects on keratinocytes demonstrated through transgenic mouse models.

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 testosterone and 5α-dihydrotestosterone induced apoptosis in dermal papilla cells from nonbalding scalp regions, suggesting a high androgen stimulus can trigger cell death related to androgenetic alopecia.

This study found that cyclosporin A treatment enhances hair growth in mice by inhibiting calcineurin-NFAT1 activity, which alters keratinocyte differentiation and apoptosis-related gene expression in hair follicles.

This study found that murine skin is a target for melatonin bioregulation, as melatonin affected DNA synthesis and tyrosinase activity in skin organ culture.

This study observed that in hormone-starved prostate cancer cells, the androgen 5alpha-dihydrotestosterone rapidly induces matriptase activation and shedding, which involves androgen receptor signaling and requires both transcription and protein synthesis.

This chapter reviews keratins in skin epithelia, including their roles in cellular function and disease, and reports no new experimental results.

This study found that polyamines enhance genome integrity by facilitating homologous recombination-mediated DNA repair, suggesting a novel role for polyamines beyond promoting cell growth and proliferation.

This study observed that nuclear β-catenin expression in non-small-cell lung carcinomas correlates with increased proliferation and loss of key cell-cycle checkpoints, suggesting an oncogenic advantage.

This study found that PNU 157706 is a highly potent inhibitor of human 5α-reductase enzymes, showing a stronger and longer-lasting antiprostatic effect in rats compared to finasteride.

This study found that combining minoxidil with all-trans retinoic acid additively promoted hair growth in vitro by activating certain cell survival pathways and reducing apoptosis markers more effectively than minoxidil alone.

This study found that high levels of parathyroid hormone-related protein expression can result in the production of shorter hair shafts, likely through effects on angiogenesis.

This study demonstrated that topical oleuropein induced hair growth in mice by activating the Wnt10b/β-catenin signaling pathway and increasing expression of several growth-related genes in skin tissue.

This study found that combining minoxidil and retinol additively promoted hair growth in vitro, enhancing Erk- and Akt-dependent pathways and preventing apoptosis in dermal papilla cells and keratinocytes.

This review discusses the unique capacity of fetal skin to heal wounds without scarring and notes that while many factors have been identified, the complete mechanism of fetal wound healing remains unclear.

This study found that hypaphorine alters cytoskeletal organization in Eucalyptus globulus root hairs, contributing to reduced root hair elongation by possibly disrupting vesicle delivery needed for growth.

This review discusses the developmental regulation of wound healing mechanisms in mammals, focusing on the role of the Wnt and TGF‐β signaling pathways, and reports no new clinical findings.

This study found that the CD44(+) ALDH(+) population of neonatal human keratinocytes exhibited enhanced stem cell properties, including significantly increased long-term epidermal regeneration and multipotency, compared to unfractionated cells.

This study observed that selectively activating activin in the epidermis of mice enhanced reepithelialization during wound healing without altering the quality of the healed wound.

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