This study found that 5% primed conditioned medium from human umbilical cord blood-derived mesenchymal stromal cells significantly improved hair density, thickness, and growth rate in patients with androgenetic alopecia.

This review discusses how inflammation influences hair follicle stem cell activities like wound healing and follicle cycling and suggests a potential link between inflammation, stem cell activation, and programmed cell death.

This study found that platelet-rich plasma may influence the proliferation of human hair dermal papilla cells by affecting gene expression related to the cell cycle.

This study found that skin-resident Treg cells regulate hair follicle stem cell proliferation and differentiation through the Jag1-Notch signaling pathway, influencing hair regeneration.

This study found that male and female chicken feather morphology and color patterns can be extrinsically modified through molting and resetting the stem cell niche during regeneration.

This study observed that adipose-derived stem cells modified with trichogenic factors have similar properties to dermal papilla cells and show enhanced hair regeneration potential compared to unmodified adipose-derived stem cells.

In this study, researchers identified gremilin-2 as a highly specific gene to the dermal sheath cup, suggesting it plays a key role in maintaining its properties.

This review discusses the role of umbilical cord-derived mesenchymal stromal cells in skin rejuvenation and reports no new clinical results; it emphasizes their potential in delaying skin aging.

This study found that the trichogenicity of cultured human outer root sheath follicular keratinocytes decreased with longer cultivation periods and was significantly influenced by the expression of the transcription factor FOXA2.

This study found that histone methylation patterns in hair follicle stem cells differ from those in embryonic stem cells.

This review examines the antitumor effects of metformin and highlights discrepancies between basic and clinical study results, noting that these may be due to different dosing levels.

This study found that Rab27a and Rab27b play opposite roles in hair growth, with Rab27a knockdown suppressing and Rab27b knockdown promoting hair growth in models.

Flutamide-induced hypospadias in rats slows down early wound healing.

This chapter reviews signaling pathways related to androgenic alopecia in dermal papilla cells of balding human scalps, integrating published information and analysis of molecular interactions, without reporting new clinical results.

This review discusses current advancements in mesenchymal stem cell-based therapies for skin repair and rejuvenation, focusing on therapeutic strategies, particularly highlighting the potential of neonatal and placenta-derived MSCs, and reports no new clinical results.

In this study of Danioninae species, researchers reported that the presence of breeding tubercles on the pectoral fins is conserved in certain species and linked to local androgen conversion, with steroid 5-α-reductase playing a crucial role in their development.

This review explores how various skin cell types contribute to photoaging driven by UV radiation, detailing their interactions and molecular mechanisms like oxidative stress and ECM degradation, ultimately offering insights for future anti-photoaging strategies.

In this study, researchers examined the methylation patterns in the skin tissues of Alpine Merino sheep with varying wool fiber diameters, finding that specific methylated RNAs linked to the Wnt, Notch, and TGF-ẞ signaling pathways may influence fiber diameter and potentially improve wool quality.

This study found that dermal papilla cell-conditioned medium can protect against UV-induced skin aging in a mouse model by modulating ferroptosis pathways, highlighting its potential for treating oxidative stress-related skin conditions.

This study found that while rat models treated with letrozole and dihydrotestosterone exhibit altered sterol, leukotriene, and steroid hormone profiles similar to human PCOS, significant differences remain.

This study found that Iraqi women with PCOS who carry the reference wild type alleles of OCT1 had a significant hormonal and metabolic response to metformin, unlike those with mutant alleles.

This study observed that extracellular matrix scaffold membranes performed less effectively in wound healing for aged mice compared to younger ones, with senescent SPP1+ macrophages potentially hindering epidermal and fibroblast repair abilities.

This study investigated the molecular mechanisms behind the formation of drug-polymer inclusion complexes and found that carbamazepine can self-assemble into stable channel structures without guest polymers, unlike griseofulvin, which requires guest molecules for structural stability.

This research elucidates the molecular mechanisms underlying carbamazepine and griseofulvin's inclusion complex channel formations with polymers, revealing why carbamazepine forms stable channels independently, while griseofulvin requires polymeric support due to weaker interactions.

This study found that hair-type tissues in hedgehogs show higher enrichment of immune-related genes compared to spine-type tissues, suggesting that spines evolved to protect against injuries and infections.

This study concludes that anti-androgenic chemicals causing short anogenital distance in male fetuses also induce a feminized transcriptional profile in the perineum, implicating Wnt and estrogen signaling in the process.

Activating the Eda/Edar pathway improves wound healing by enhancing hair follicle growth.

This study found that a 22-bp InDel polymorphism in the FGF7 gene was significantly associated with growth traits in goats, with genotypes ID and/or II linked to better growth compared to genotype DD, indicating its potential as a molecular marker in breeding programs.

This study found that zebrafish with a mutation in the GDP-fucose biosynthesis gene exhibited enhanced and faster regeneration of mechanosensory hair cells, implicating the importance of this gene and Notch signalling regulation in hair cell regeneration mechanisms.
