This study found that inhibiting neurosteroidogenesis affected GABA A receptor-mediated synaptic inhibition in immature rats but not in adults, suggesting age-dependent modulation of synaptic strength in the spinal dorsal horn.

This review examines the neuroendocrine mechanisms underlying seasonal changes in mammals and highlights areas needing further research, reporting no new experimental results.

This case report describes a newly identified condition called loose anagen hair of childhood, characterized by easily pluckable hair in two young boys, with variable duration and no scalp inflammation or scarring.

This review discusses strategies for regenerating cutaneous nerve function in burn patients and highlights the potential role of autologous skin-derived adult stem cells in improving sensory recovery, but reports no new experimental findings.

This study found that mouse skin can produce and metabolize serotonin and N-acetylserotonin, with activity influenced by location, physiological skin status, cell type, and mouse strain.

This review explores embryonic epidermal development and discusses key molecular regulators and roles of the sub-epidermal mesenchyme, but reports no new experimental results.

This study found that stimulating the olfactory receptor OR2AT4 in human hair follicles with a synthetic sandalwood odorant promotes hair growth ex vivo by decreasing apoptosis and increasing IGF-1 production.

This study suggests that the GPX-PDE1 and GPX-PDE2 genes in white lupin enhance root hair development and contribute to Pi limitation acclimation by facilitating glycerophosphodiester degradation.

This review highlights the potential of extracellular vesicle-based therapies for treating various diseases, but it also notes challenges like the lack of regulatory guidelines that hinder their clinical development.

This study found that sympathetic nerves and arrector pili muscles form a niche that modulates hair follicle stem cell activity, revealing their role in hair follicle regeneration.

This review discusses the impact of menopause-related oestrogen deficiency on skin ageing and suggests that oestrogen use may improve collagen and skin elasticity, but it reports no clinical trial results.

This study found that Sonic Hedgehog secreted by hair follicle transit-amplifying cells is essential for dermal adipogenesis and hair follicle growth by acting on adipocyte precursors.

This review discusses the synthesis and biological activities of jasmonates, highlighting their potential as drugs and prodrugs, but reports no new clinical results; further research and trials are anticipated.

This study found that human hair follicle-derived mesenchymal stem cells can differentiate into myogenic, osteogenic, adipogenic, and chondrogenic lineages, although this potential decreases over time and varies by lineage.

This review provides an overview of current research on AD-MSCs, PRP, and biomaterials, highlighting their safety and efficacy in treating soft tissue defects and chronic wounds without major side effects.

This review discusses the development of electrospun nanofibrous scaffolds for promoting angiogenesis in tissue engineering but notes that their clinical application beyond bone and skin repair is still limited.
