This study demonstrated that human skin can be efficiently reinnervated using human induced pluripotent stem cell-derived neural stem cells, promoting skin vitality and sensory reinnervation comparable to physiological conditions.

This study found that autologous γdTregs displayed significant protective effects on alopecia areata-affected human scalp hair follicles in both ex vivo and in vivo settings, suggesting potential for future cell-based therapy.

This study concluded that ACT injections, alone or combined with finasteride, have significant therapeutic effects and safety in treating androgenic alopecia, with promising clinical potential.

This study suggests that high proliferative activity and peripheral invasion are key indicators of malignancy in canine sebaceous gland tumours. It also reports a higher incidence of circumanal gland and testicular tumours, indicating a possible androgen-related pathway in tumour development.

This review explores the molecular mechanisms through which NGF may enhance burn wound healing by reducing healing time and improving scar quality, but it presents no new clinical results.

This study developed immortalized human hair follicle-derived mesenchymal-like stromal cells (iHF-MSCs) as a consistent source of therapeutic secretome, reporting their superior immunomodulatory and regenerative performance, potentially advancing cell-free therapies for inflammation and tissue repair.

This study found that a biomaterial gel made from human hair keratins facilitated nerve regeneration in an animal model, potentially matching the effectiveness of traditional autografts.

Human hair follicles have a unique cell distribution and differentiation pattern during growth.

This study found that SM04755, a novel topical drug, inhibited inflammation, keratinocyte proliferation, and fibrosis in vitro and improved skin health in a mouse model of psoriasis, indicating potential as a topical psoriasis treatment.

This review highlights the critical role of neuroregulation in skin wound healing, emphasizing how neurotransmitters and neuropeptides regulate inflammation, angiogenesis, and cell proliferation, and discusses potential therapeutic strategies, such as neuromodulation, to enhance these processes.

This article discusses the role of growth hormone, insulin, and IGF-1 in acne development and highlights how diet and syndromic evidence support their involvement, but presents no new clinical findings.

This study found that alopecia areata patients who responded poorly to topical immunotherapy had impaired peripheral blood mononuclear cell responses to T-cell stimulants.

In this study, transplantation of rat hair follicle stem cells significantly improved sciatic nerve regeneration and muscle function in nerve-injured rats.

In this study, FOL-026, a peptide based on osteopontin, was shown to promote angiogenesis and stimulate vascular cell proliferation and migration through neuropilin-1, similar to VEGF, suggesting potential therapeutic applications in vascular repair and angiogenesis-related conditions.

In this study, keratin hydrogels derived from human hair were found to significantly enhance nerve regeneration in a mouse model, acting effectively as scaffolds by influencing Schwann cell behavior.

This study found that two synthesized androst-4-ene-3-one derivatives, 6f and 6g, exhibited stronger anti-proliferative effects than common drugs on prostate cancer cell lines, with low toxicity to rat cells.

This review discusses the potential of hair follicle stem cells as a novel source for cell therapy in neurodegenerative disorders, but it reports no new clinical results.
