This review discusses recent advances in using extracellular vesicles as a potential treatment for alopecia and highlights ongoing challenges in their clinical application and mass production; no new clinical results are reported.

In this study, researchers used two dermal papilla spheroid models to investigate hair cycle regression mechanisms and found that the vascular system enhances tissue physiology and gene modulation, while Retinol-based treatments can partially recover tissue degeneration observed over an extended culture period.

This review examines the mechanisms, recent findings, and strategies to enhance mesenchymal stem cells' therapeutic effects in skin wound healing, but reports no new research results.

This review discusses recent insights into the dynamics and regulation of the epidermal differentiation complex during keratinocyte differentiation and reports no new experimental results.

This study found that although three-dimensional bioprinting in plastic and reconstructive surgery is rapidly advancing, complete tissue systems have not yet been successfully printed due to ongoing challenges.

This review discusses the genetic pathways involved in melanoma and suggests that targeting these pathways with pharmacological inhibitors may provide a new therapeutic approach, though clinical results have been disappointing so far.

This paper presents an interactive quiz related to a study by Deng et al. (2022) in the Journal of Investigative Dermatology, examining androgen receptor-mediated paracrine signaling in androgenetic alopecia, but it provides no new clinical findings.

This study developed a hydrogel dressing incorporating angelica polysaccharides, demonstrating enhanced wound healing properties in a mouse model by promoting rapid hemostasis, tissue healing, and new blood vessel formation compared to Tegaderm™ film.

This study introduces the term "hair matrix cyst" for a cyst with both pilomatricoma and epidermal cyst characteristics, highlighting its potential for misdiagnosis among similar skin conditions.

This case report describes the first instance of juvenile hemochromatosis type 2A associated with secondary hypothyroidism, linked to a novel mutation in the HJV gene.

This review discusses Hutchinson-Gilford Progeria Syndrome, its symptomatology, and the progress in developing treatment strategies, emphasizing that while a cure remains elusive, advances in understanding the disease's molecular mechanisms show promise for future approaches.

In this study, researchers developed a microfluidic-assisted technology to create dual-layer microspheres containing mesenchymal and epidermal cells, which efficiently induced hair follicle regeneration in mice, suggesting potential improvements for hair regeneration treatments in conditions like androgenetic alopecia.

This case study reports an Asian female with congenital adrenal hyperplasia presenting atypically with polymenorrhagia, who showed improvement with oral dexamethasone, despite no change in hirsutism or clitoromegaly.

In this study, the researchers compared the pharmacokinetics and tissue distribution of dihydroartemisinin in nanostructured lipid carriers versus in solution, finding longer mean residence times and variable organ accumulation with the nanostructured lipid carriers.

This study found that the dehydroepiandrosterone hydroxylating enzyme system in hair follicles is similar to the liver monooxygenase system, sharing characteristics such as inhibition by carbon monoxide and dependency on NADPH.

This study demonstrated that a single multimode fiber can be used for single-shot wide-field reflectance imaging, achieving high correlation with the ground truth and enabling real-time microendoscopy at up to 180 frames per second.

In this study, carboxymethylalanyl disulfide keratin was shown to effectively prevent hair damage during repeated bleaching and permanent waving treatments.

People with X-linked hypohidrotic ectodermal dysplasia have no sweat ducts and less, thinner hair.

This study developed a reliable RP-HPLC-DAD method, finding that amino acid concentrations in bleached hair decrease with higher hydrogen peroxide levels, notably affecting cystine.

Intense pulsed light with radiofrequency showed mixed results in improving quality of life for hidradenitis suppurativa patients, with no clinical improvements.

This review found no evidence that DHEA improves quality of life or decreases menopausal symptoms in peri- and postmenopausal women, but it may slightly enhance sexual function compared to placebo.

This study introduced an eco-friendly enzymatic hair dyeing process utilizing laccase-catalyzed polymerization of hematoxylin, achieving intense, long-lasting color comparable to commercial dyes while enhancing hair strength and offering antioxidant and UV-shielding benefits.

This study found that patients with hidradenitis suppurativa had significantly higher levels of cell-free DNA in their serum compared to healthy controls, suggesting its potential as a biomarker for the disease.

In this study, prenatal ultrasonography was found to be a valuable tool for screening ectodermal dysplasia during pregnancy, and a new EDA gene variant associated with X-linked hypohidrotic ectodermal dysplasia was identified, aiding in more accurate diagnoses and reproductive decision-making.

This study found that the hairless gene product (Hr) suppresses VDR-mediated gene activation by directly interacting with the vitamin D receptor, potentially affecting hair follicle function.

In this study, the researchers developed a new method using H2O2/TiO2/UV for extracting human hair keratins rapidly, yielding higher protein and enabling the production of keratin films with better hemostatic performance and varied wound-healing properties compared to films from traditionally extracted keratin.

This study found that human hair follicle-derived mesenchymal stem cells effectively maintained human embryonic stem cells in an undifferentiated state, comparable to mouse embryonic fibroblasts under standard conditions.

This review discusses the role of RDH12 in vision, its structural and functional aspects, and related disease mechanisms, but reports no new clinical results; it aims to support therapy development for inherited retinal dystrophies.

This study found that preconditioning adipose-derived stem cells with HB-EGF enhanced their ability to promote hair growth in vivo by increasing their motility, paracrine effects, and survival.

This study found that subcutaneous injection of medroxyprogesterone acetate was more effective than intramuscular or topical treatments in reducing hair diameter for hirsute females.
