In this study, human dermal fibroblasts were identified as natural host cells that support productive Merkel cell polyomavirus infection, and the MEK antagonist trametinib was introduced as an effective inhibitor to control the virus.

This study observed dynamic behaviors such as cluster formation, migration, and active proliferation of transplanted bone marrow cells in a mouse model, providing insight into cellular-level changes post-transplantation.

The new surgical technique for vitiligo is effective, safe, and cost-efficient.

This study reports that hedgehog pathway inhibitors, sonidegib and vismodegib, showed distinct adverse event patterns in real-world data, suggesting the need for further research to confirm these findings.

In this study, microneedling radiofrequency followed by topical exosome application was associated with significant increases in hair density and diameter, showing promising potential as a therapy for pattern hair loss.

This study suggests that the growth arrest of nevus melanocytes is not due to oncogene-induced senescence but rather to collective cell interactions, similar to those in normal tissue size regulation.

This study reports no results yet and only indicates an ongoing randomized placebo-controlled trial investigating the effects of microneedling combined with topical dutasteride solution for treating androgenetic alopecia.

This study introduced a volar skin excisional wound model that closely mirrors human wound healing and supports evaluation of skin regeneration with multiple appendages and innervation.

This review discusses the pharmacological properties of 4-0-methylhonokiol from Magnolia species and reports no new experimental results, highlighting potential areas for future research.

In this study, N. ottonis cactus cell extract applied to mice promoted hair growth and increased the number of hair follicles, suggesting its potential as a hair-growth-promoting agent.

This study found that Dex-loaded hyaluronic acid hydrogel microneedles significantly reduced pain in an acute inflammatory visceral pain model without sedation, suggesting a promising and patient-friendly alternative to intravenous delivery.

This study identified NM_026333 as a potential anti-aging gene that, when induced, may alleviate proton-induced aging symptoms in CF6-overexpressing and high salt-fed mice.

In this study, researchers developed grooved microneedles made from hyaluronic acid for precise transdermal drug delivery, achieving accurate dosage with a high probability of delivery (98% or more) by using an easy-to-operate applicator for shearing force.

This article reviews approved treatments for androgenetic alopecia and reports no new research findings, highlighting the need for further studies.

This case study reports a novel mutation in the TRPV3 gene causing atypical Olmsted syndrome, characterized by disabling keratoderma and squamous cell carcinoma, highlighting the need for careful long-term monitoring in affected patients.

This study found that cutaneous squamous cell carcinomas in mice infected with murine papillomavirus preferentially arise from Lgr5+ progenitor cells, while squamous cell dysplasia does not.

This study reported that optimized transfersomes and their gel form significantly improved transdermal delivery and hair growth promotion of minoxidil in C57BL/6 mice compared to commercial formulations.

This study found that miR-124 may facilitate the differentiation of hair follicle stem cells into neuronal cells by targeting Sox9 and Ptbp1.

In this study, niosomal formulations enhanced minoxidil skin accumulation compared to commercial and control solutions, suggesting a potential improvement for topical delivery in hair loss treatment.

This study reports that patients with specific MFN2 mutations, including p.Arg707Trp, exhibit significant upper body fat overgrowth with suppressed leptin production, suggesting tissue-selective mitochondrial dysfunction and potential therapeutic targets.

This review discusses advancements in skin microphysiological systems, such as 3D bioprinting, skin organoids, and skin-on-a-chip, and their effectiveness in emulating human skin functions for research and preclinical applications, highlighting the potential for replacing animal testing with these innovative technologies.

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.

This study found significant hair growth improvement with microneedling radiofrequency treatment in most patients with patterned hair loss, with minimal short-term adverse effects.

Among in vitro and in vivo models, this study found that Miscanthus sinensis var. purpurascens flower extract may promote hair growth, potentially by modulating growth factor expressions and facilitating earlier hair follicle transitions in treated mice.

This review discusses recent advances in understanding Merkel cell carcinoma biology, including the development of genetically-engineered mouse models and potential therapeutic targets, but reports no new clinical results.

This study demonstrated that ND-GFP stem cells from the hair-follicle bulge area can differentiate into various cell types, including neurons, suggesting their potential as a source for therapeutic applications.
