In this study, ritlecitinib treatment for 12 and 24 weeks downregulated immunity-related genes and upregulated hair keratin genes in patients with alopecia areata, correlating with scalp hair regrowth response.

In this study, researchers used tissue clearing techniques on human skin and scar tissue for the first time to render them optically transparent, with the aim of revealing atypical structures and improving protocols for observing scar tissue changes.

This study found that human meibomian glands differ significantly from free and hair-associated sebaceous glands in morphology and lipid composition, making them highly specialized holocrine glands.

The study found that adipose-derived mesenchymal stem cells obtained via laser-assisted liposuction with selective photo-stimulation are comparable in differentiation potential and tumorigenic risk to those from conventional liposuction for cell therapy applications.

This review updates on various methods for hair and scalp examination, encompassing non-invasive, semi-invasive, and invasive techniques, and reports no new results.

Vitamin D3 affects cell differentiation in specific skin areas.

This study found that mesenchymal stem cells, especially when injected intradermally, significantly accelerated wound healing in rats compared to chitosan treatment.

This study found that ethanolic leaves extract of Hibiscus rosa-sinensis L. exhibited strong antioxidant activity and enhanced wound healing properties in mice, showing reasonable safety in toxicological evaluations without severe alterations.

This study reports that a new protocol using Angio PRP improved wound healing in mice by enhancing key healing processes and regulating inflammation, suggesting potential for clinical advancements.

This study found that mesenchymal cells in mouse and chicken embryonic skin undergo a process of migration driven by tissue tension and WNT secretion, influencing their dispersal and integration into dermal condensates.

This case report describes a hybrid cyst in a Sprague-Dawley rat, showing both infundibular and matrical differentiation similar to different parts of normal hair follicles.

This study in rats with a portocaval shunt observed severe ultrastructural damage to the inner ear, associated with zinc deficiency and symptoms resembling liver cirrhosis in humans.

This study found that bimatoprost eye drops increased eyelash length, thickness, pigmentation, and the number of eyelashes per follicle in rabbits, without causing inflammation.

This study identified core genes and pathways involved in androgenetic alopecia, finding that genes related to hair follicle development are down-regulated, while those linked to immune responses are up-regulated, highlighting potential therapeutic targets.

This study identified collagen XXII as a novel extracellular matrix protein specifically present at tissue junctions, where it functions as a cell adhesion ligand for skin epithelial cells and fibroblasts.

This study found that human adipose tissue-derived mesenchymal stem cells inhibited A549 tumor growth but significantly promoted HT-29 tumor growth in mouse models, highlighting opposing effects depending on the cancer type.

This study analyzed the molecular evolution and functional divergence of the Dkk gene family, finding accelerated evolution in Aves and Reptilia and identifying functional differences that may impact hair follicle development via Wnt signaling inhibition.

In this rare case report, the researchers described a 66-year-old African woman with lipedematous alopecia, highlighting its clinical features, the significance of palpation in examinations, and the uncertainty of it being a distinct disease entity or a combination of two conditions.

This study observed that using an environmentally friendly bovine milk permeate effectively and cleanly removes wool from sheepskins without harming the skin, and results in smoother leather compared to traditional chemical methods.

This study found that TGFbeta is a key pathway causing age-related loss of dermal fat's antimicrobial function, suggesting that targeting TGFBR might help restore skin defense against infections in older age.

In this study, BP201, derived from porcine lung phospholipids, promoted hair growth in mice, especially when combined with minoxidil, and increased hair follicle numbers and dermal papilla cell proliferation.

This study found that in mice, knockout of Rac1 and Rac3 in keratinocytes led to reduced white adipose tissue and revealed Rac-dependent paracrine pathways affecting pre-adipocyte differentiation.
