This study found that neonatal finasteride treatment in male rats altered hippocampal GABAA receptor subunit expression and led to increased anxiety-like behavior in response to progesterone in adulthood.

This study found that micro-current electrical stimulation may promote hair growth in human hair follicle-derived papilla cells and a mice model by enhancing cell proliferation, migration, and activating key growth pathways.

In this study using diabetic rat models, the combination of AMD3100 and low-dose FK506 reduced wound healing time and improved microcirculation in diabetic foot ulcers, indicating a promising new systemic therapy.

In a porcine model, this study observed that using an External Tissue Expansion Device increased epidermis thickness, cell proliferation, and vessel density at fat graft recipient sites.

This study found that novel RNA aptamers specifically inhibited FGF5-induced cell proliferation, suggesting their potential as candidates for treating FGF5-related diseases or hair disorders.

This study reported that a novel chitosan/polyvinyl alcohol nanofiber sponge effectively enhances the hair follicle-inducing ability of dermal papilla multicellular spheroids in a mouse model.

This study found that low-level laser treatment may promote hair regrowth in mice by activating the Wnt10b/ß-catenin pathway and inducing the anagen phase of hair follicles.

This study developed and validated a label-free assay using LC-MS to screen for S5αR inhibitors, identifying Thai herbal extracts, Impatiens balsamina L. and Curcuma longa L., as promising sources.

This study found that forming spheroids using silicone micro-wells improved the viability and neural differentiation potential of human adipose-derived stem cells after thawing.

This study found that the yeast androgen screen (YAS) could detect the activity of methyltestosterone in urine for a longer period than classical GC/MS, potentially identifying long-lasting metabolites.

This study suggests that human embryonic stem cells may improve skin graft quality and functionality by enabling the identification and amplification of early ectodermal progenitors, pending confirmation from preclinical studies.

In this study involving a mouse model, researchers reported that intranasal delivery of protein-based CRISPR/dCas9 nanoparticles targeting the gene *Sirt1* reduced cerebral edema and increased survival following ischemic stroke, with no significant toxicity observed.

This study found that Centipeda minima extract promotes hair growth by activating Wnt/β-catenin, ERK, and JNK signaling pathways in human hair follicle dermal papilla cells.

In this study, applying deer antler velvet extract-loaded niosomes and microspicules serum to the scalp significantly improved hair growth, melanin content, and skin hydration over 14 to 30 days without causing skin irritation.

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.

This study found significant changes in gene and protein expression related to hair follicle development in Rex rabbits' skin during the first 8 weeks of life.

In this study, EGCG from green tea promoted mink hair follicle growth and cell proliferation at specific concentrations, potentially through activation of Shh and AKT signaling pathways.

This study found that male 5α-reductase 2 knockout mice showed deficits in social dominance behaviors and reduced dopamine receptor binding in a brain region related to social ranking.

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.

This study found that while autonomous Sema3A expression limited keratinocyte migration and delayed wound healing, non-autonomous application of recombinant Sema3A with EGF enhanced wound repair in mice.
