This case report observed that treatment with human placental mesenchymal stromal cell-derived exosome-enriched extracellular vesicles may improve symptoms of chronic cutaneous graft-versus-host disease, including hyperpigmentation and skin ulcers, in a patient resistant to conventional therapies.

In this study, individualized homoeopathic treatment with Silicea showed a marked reduction in depigmentation for a case of vitiligo, with a likely causal link suggested by evaluation criteria.

This report describes a case of secondary cutis verticis gyrata due to a cerebriform intradermal nevus, highlighting clinical management and screening guidelines.

This case report describes a 36-year-old woman with hidradenitis suppurativa whose condition progressed to rapidly fatal squamous cell carcinoma, highlighting the potential for aggressive tumor development linked to specific protein markers.

This study found that despite challenges, a combination of oral antibiotics, anti-androgens, oral retinoids, biologics, and surgery were important in managing hidradenitis suppurativa in patients with intellectual and developmental disabilities.

Hair follicle stem cells can become heart muscle cells.

This systematic review and meta-analysis found that hidradenitis suppurativa is associated with an increased risk of major adverse cardiac events, including cerebrovascular accidents and myocardial infarction, although study heterogeneity affects the magnitude of risk.

This study found that Hoxc gene expression can reprogram mesenchymal dermal papilla cells, enhance epithelial stem cell regenerative potential, and promote region-specific hair follicle regeneration through Wnt signaling.

This review discusses the integration of ultrasound in dermatology for improved lesion visualization and diagnosis, highlighting recent technological advancements like handheld devices and high-frequency probes, and reports no clinical results.

This study found that the current approval processes by major regulators like the EMA and FDA for HPV vaccines may rely on only half of the available trial data.

This case report details a 25-year-old woman with progressive scalp hair loss, extensive baldness, and facial hirsutism since adolescence, despite normal libidinal desires and body weight.

This study identified two distinct VDR gene mutations among Lebanese families with hereditary vitamin D-resistant rickets, noting varied treatment responses and promising outcomes despite severe phenotypes.

This review discusses the role of HPV vaccination and early screening in reducing cervical cancer incidence but reports no new clinical results.

This paper discusses the use of Digital Volumetric Imaging with fluorescent dyes to visualize and compare the interior structures of six different virgin hair types, reporting no new clinical results.

In this study, transient transfection of the HIF-1α gene into fibroblasts led to increased VEGF expression, which may enhance the growth and anagen phase of human hair follicles in vitro.

In this rat study, HHK implantation after spinal cord injury did not significantly improve locomotion but may have integrated into the spinal tissue, potentially aiding recovery and reconstruction.

The researchers investigated a Maine Coon cat with suspected classical Ehlers-Danlos Syndrome and discovered a heterozygous deletion in the COL5A1 gene, underscoring the value of whole-genome sequencing for precise veterinary diagnostics.

Human hair follicles have their own thyroid hormone system.

This study identified the Hairless (Hr) gene-encoded protein as a corepressor that plays a crucial role in maintaining skin and hair by regulating epithelial stem cell differentiation and gene expression via chromatin remodeling, which may impact both development and disease.

This article reviews the role of the hairless protein in hair cycling and gene regulation, noting the need for further understanding of its JmjC domain and subcellular localization roles.

This research consisted of a Phase I/II study on androgenetic alopecia where male participants received intradermal injections of HSC, with hair growth efficacy assessed through Trichoscan imaging, although no new clinical results are reported.

This study found that ultraviolet light-enhanced visualization can detect subtle skin changes linked to carotene and vitamin A deficiency, which improved with dietary correction in deficient individuals.

Veratric Acid may help promote hair growth and reduce hair loss.

In this study, transcutaneously applied nanoparticles and viral vectors were shown to penetrate murine hair follicles, internalize in antigen-presenting cells, and induce immune responses, suggesting a promising approach for vaccine delivery.

In this study, researchers developed a dexpanthenol-infused nanotechnological platform within hyaluronic acid hydrogels that promoted wound healing in mice by providing a protective barrier and significantly enhancing skin regeneration, including increased fibroblast activity and tissue remodeling.

This case report describes a 29-year-old male with relapsing hepatitis A, a rare complication of acute hepatitis A virus infection, characterized by prolonged elevated liver chemistries and persistent HAV IgM, managed conservatively.

This study found that the absence of the vitamin D receptor disrupts hair follicle structure during the first catagen in mice, linked to increased expression of the hairless gene.

This study presents a novel in vitro assay using human folliculoid microspheres to research hair growth, which may facilitate preclinical testing of hair growth-modulatory agents.

This study observed that tissue-engineered skin, using VEGF165 gene-modified cells embedded in astragalus polysaccharide-containing 3D printed scaffolds, enhanced early vascularization, and collagen and hair follicle regeneration, leading to improved skin repair in nude mice with full skin defects.

This study developed a validated murine model of hypertrophic scar contraction, demonstrating similarities to human skin and observing graft contraction and tissue characteristics over time.
