This study found multipotent progenitors in sweat ducts that become unipotent after sweat gland development, highlighting distinct regenerative capabilities in adult glandular skin stem cell populations.

This study found that ZnO nanoparticles in topical skin products do not penetrate beyond the outer skin layers in humans, suggesting minimal safety concerns for subdermal absorption.

This study found that Wnt signaling in the hair follicle is crucial for coordinating the behavior of epithelial and melanocyte stem cells, which drives hair regeneration and melanocyte differentiation in mice.

This study identifies mutations in the SRD5A3 gene as a cause of a new type of congenital disorder of glycosylation, impacting mental, ophthalmologic, and cerebellar functions.

This study found that altering cell culture conditions to form three-dimensional papilla spheroids can restore the ability of human dermal papilla cells to induce hair growth in adult skin.

This study demonstrates that bioengineered lacrimal gland germs can successfully develop and restore tear production and ocular surface protection in a mouse model with lacrimal gland dysfunction.

This review discusses the preclinical and clinical data on teriflunomide for multiple sclerosis, highlighting its selective action on immune cells without causing clinical immune suppression, and provides no new clinical results.

This research found that Foxc1 transcription factor and COL17A1 are critical in regulating quiescence and hair thinning in hair follicle stem cells, with aging-related DNA damage leading to hair loss.

This study found that adipocytes play a crucial role in skin wound healing by facilitating fibroblast recruitment and dermal reconstruction during the healing process.

This study found that neurosteroids can reorganize GABA A receptors in mice, mimicking ovarian cycle changes, with the process being mediated by neurosteroid levels rather than direct hormone receptor activation.

This study found that many effects previously thought to be caused by circadian rhythm disruption in Bmal1 knockout mice are actually due to BMAL1's properties unrelated to its clock function.

This study found that fibroblast growth factor 9, initially secreted by γδ T cells, plays a key role in modulating hair follicle regeneration in mice after skin wounds.

FPHL affects hair density and diameter, causing visible hair loss in older women.

This review explores possible reasons for why male COVID-19 patients experience more severe symptoms and higher fatality rates than female patients but provides no new clinical results.

This review examines the role of nerves in regeneration across various species and discusses their importance as components in the progenitor cell niche, reporting no new clinical results.

This review discusses recent advances in microfabrication and microfluidic technologies for improving the production of organoids and spheroids, but it reports no new experimental results.

This research overview highlights that although JAK inhibitors show promise as potential treatments for alopecia areata based on recent insights into the disease mechanism, their efficacy has not yet been thoroughly evaluated in a systematic manner.

This review discusses the mechanisms and potential therapeutic benefits of mesenchymal stromal cell-derived extracellular vesicles delivered via biomaterials, but reports no new clinical results.

This review provides a comprehensive overview of melatonin's physiological roles, effects, and clinical implications, but it does not present new experimental findings.

This study found that PM2.5 exposure induced oxidative stress in human keratinocytes and mouse skin, causing cellular damage, which was mitigated by the antioxidant N-acetyl cysteine.

This article presents a comprehensive guide for classifying human hair follicle cycle stages in vivo using scalp xenografts on immunocompromised mice, offering valuable resources for researchers in the field.

This study identified a set of wound-induced genes in planarians that play a role in regeneration initiation, with some genes specifically activating within regenerative cells called neoblasts.

In this study, researchers found that the number of dermal papilla cells in hair follicles determines hair size and shape in mice, suggesting potential avenues for addressing hair loss.

This study found that the BMP antagonist noggin induces hair growth in postnatal skin by neutralizing BMP4's inhibitory activity, potentially mediated by changes in Shh expression.

The researchers described a chip-based bioreactor platform for dynamic perfusion, which may enhance in vitro skin models by introducing mechanical shear stress and extending culture periods.

This study found that dermal papilla and peribulbar dermal sheath cup cells in mice can both induce hair follicle formation, suggesting they may have similar functional roles in hair growth.

In this mouse study, researchers found that dermal Wnt signaling/β-catenin activity is essential for fibroblast proliferation and initiating hair follicle formation by interacting with epidermal Wnt ligands.

PGD2 stops hair growth and is higher in bald men with AGA.

This study describes a system for generating hair follicles from dissociated cells in mice, suggesting that successful development requires a foundational epithelial platform.

This study concluded that current cross-sex hormone treatments for trans men and trans women are effective with a low risk of side effects in the short term, though they did observe specific clinical changes.
