This study reported that a Megsin-Cre transgene enables genetic manipulation primarily in skin, forestomach, and esophagus tissues, offering a new tool for studying development and diseases in these areas.

This study found that peptidylarginine deiminase type III and trichohyalin are coincidentally expressed in the infant rat hair follicle, but trichohyalin deimination occurs after their expression during development.

This study explored the molecular biology of skin adaptations in pangolins, revealing that certain genes for lipid synthesis have inactive patterns, while others related to skin function remain intact, suggesting complex evolutionary changes in their skin physiology.

The document concludes that the skin is a complex organ providing protection, sensation, and healing, with challenges in treating conditions like itchiness.

In this study, the researchers reported the detailed anatomical structure of horse skin, including the composition and organization of the epidermis, dermis, and associated glands and follicles.

This study found that proretinal nanoparticles, applied topically, are safe and effective for penetration into hair follicles, enhancing retinoid biological activity in the skin while reducing irritation compared to conventional retinal formulations.

This chapter reviews the presence and roles of stem cells in various body systems, focusing on their lifelong function in animals and humans, and reports no new experimental findings.

This chapter reviews the skin's structure and its clinical relevance, highlighting connective tissue diseases and the potential for novel treatments like protein, cell, or stem cell transfer, but reports no new findings.

This review outlines the histological structures of the skin, highlighting species and regional differences in dermal absorption and obstacles encountered in toxicological assessments due to epidermal thickness variability, contact dermatitis reactions, and stem cell vulnerabilities.

The researchers developed a technique for processing and staining free hair samples using paraffin embedded blocks, revealing that routine staining does not color the enucleated cuticle, while the cortex and medulla show distinct colorations when stained.

This study found that using cultured mesenchymal stem cells from mouse whisker hair follicle outer root sheath in wound healing reduced inflammation, accelerated closure, and resulted in less hypertrophic scarring in mice.

This study found that radiofrequency microneedling is effective and well-tolerated for improving various skin conditions, showing comparable efficacy to fractional lasers for atrophic acne scars with generally favorable patient satisfaction and safety.

This study demonstrated that gene-corrected 3D skin constructs from RDEB patient-derived iPSCs, grafted onto immunocompetent mice, showed normal collagen VII expression after two months.

This study found that both 5-ALA and Photofrin can effectively destroy human microvascular endothelial cells in vitro and cause tissue necrosis in vivo, with Photofrin showing greater efficacy at lower concentrations or power densities.

In this study, the researchers observed that inducing and then withdrawing β-catenin expression in a bigenic mouse model caused reversible changes in skin morphology, indicating dependence on β-catenin signaling.

This review summarizes current knowledge on tight junctions in mammalian skin and their role in drug delivery and interaction with other barrier components, but reports no new experimental results.

This study demonstrated that a 3D air–liquid culture system using Wnt-CM-treated cells can induce hair regeneration in nude mice and may facilitate large-scale preparation for hair loss treatment.

This study found that horizontal sections of scalp biopsies in patients with Central Centrifugal Cicatricial Alopecia often reveal follicular miniaturization, inflammation, and scarring, which can guide personalized treatment.

This collection of review articles discusses complications in facial plastic surgery, covering both cosmetic and reconstructive procedures, and reports no new research findings.

Junctional proteins stabilize the inner root sheath and connect the companion layer in human hair.

In this study, researchers observed significant differences in hair follicle microbiome diversity and microbial composition between hair loss and healthy groups, uncovering specific patterns and functional changes associated with female pattern hair loss, which may aid future targeted approaches for androgenetic alopecia.

This review discusses the chemical stability of protein envelopes found in the epidermis and other stratified squamous epithelia, but reports no new clinical results.

This study found that lysine carboxymethyl cysteinate helps protect the epidermis from UVB-induced damage by activating autophagy and restoring cornification processes in a skin model.

This review discusses the role of TGM3 in skin and hair follicle biology, human tumor pathology, and genetic abnormalities, and reports no novel results; the authors highlight its potential as a cancer diagnostic biomarker.

In this case report, a 31-year-old male using topical minoxidil for androgenic alopecia developed diplopia and increased intraocular pressure, which improved after stopping minoxidil and using prostaglandin analogues, although a carbonic anhydrase inhibitor caused IOP to rise again during follow-up.

This study describes the structure and composition of the epidermal horny layer in elephant seals, noting that its keratinized cells are attached without a specialized fission zone, differing from the sloughing mechanism in reptiles.

This study reports that human eccrine sweat gland cells are capable of forming a stratified epidermis, suggesting they may serve as an additional source of keratinocytes for skin repair.

In this study, researchers found that the absence of type I or type II keratins in mice leads to severe skin barrier defects, highlighting keratins' crucial role in epidermal structure and function.

This study demonstrates that PAD1 and PAD3 are involved in hair follicle differentiation, while PAD1 and PAD2 may play a role in the physiology of sweat glands and arrector pili muscles.

This study suggests that the structure and function of the inner root sheath in mammalian hair may have evolved from simpler forms seen in monotremes, aiding in hair exit without damaging the epidermis.
