This review discusses the application of liposomes in dermatology, highlighting their therapeutic value for drug stabilization, skin penetration enhancement, and treatment of hair follicle-associated disorders, but reports no new clinical results.

This study found that reduced cell cohesiveness in eccrine sweat gland outgrowths contributed to delayed wound healing in elderly skin compared to younger skin.

This study reported that transgenic mice with targeted TNF alpha expression in keratinocytes showed impaired weight gain, retarded hair growth, and skin changes, leading to cachexia and necrosis.

This study found that transplanting autologous scalp follicular grafts into chronic leg ulcers led to a greater reduction in ulcer size compared to non-grafted areas, suggesting a promising therapeutic alternative.

This study indicates that reduced activity of the matriptase-prostasin proteolytic cascade is likely the cause of human autosomal recessive ichthyosis with hypotrichosis, as demonstrated using a novel mouse model.

In a controlled study, researchers observed that lambs exposed to colder temperatures had increased wool growth, thicker skin, altered physiological traits, and activated specific molecular pathways, highlighting potential targets for enhancing cold tolerance, welfare, and productivity in sheep breeds.

This study reports that eccrine sweat glands in mice predominantly develop on the footpads, offering a reference for skin research involving genetically engineered mice.

This case report describes a 10-year-old girl with lamellar ichthyosis who showed marked improvement in scaling and skin stiffness after six weeks of treatment with emollient and supportive therapy.

This review discusses the significant role of Wnt signaling in skin development, homeostasis, and disease, highlighting recent advances in understanding its diverse functions, but reports no new experimental results.

In this study with mice, simultaneous inactivation of Smad4 and PTEN genes led to rapid development of invasive forestomach squamous cell carcinomas, mirroring human esophageal SCCs.

In this study, the deletion of Smad4 and PTEN genes in mice was associated with rapid and invasive squamous cell carcinoma formation in the forestomach, modeling human esophageal cancer progression.

Activating the Eda/Edar pathway improves wound healing by enhancing hair follicle growth.

This article discusses the role of stratum corneum disruption in dandruff and suggests that treatments improving scalp barrier integrity along with antifungal activity may be beneficial; it reports no new research findings.

This study found that Tsukushi facilitates wound healing in mice by regulating macrophage function and myofibroblast differentiation.

In this study, noncultured autologous skin cells prepared using a tissue homogenizer significantly improved burn wound healing in rats compared to a control treatment.

This study concluded that the inner root sheath inhibits the expression of certain differentiation markers in hair bulbs, with calcium-induced changes paralleling those seen in hair follicle mid-segments.

In this study, an infection model using rabbits was developed for dermatophytosis by inoculating macroconidia of Microsporum species, showing that direct intradermal application effectively progressed to the skin invasion phase and highlighted the correlation between severity of symptoms and duration post-inoculation.

This study found that elastin-like recombinamer (ELR) wound dressings promote tissue regeneration and stability without rejection in ex vivo and in vivo models, indicating potential for hard-to-heal wound treatment.

New materials and methods could improve skin healing and reduce scarring.

In this study, biotin supplementation was found to significantly increase wool follicle viability and metabolic activity in vitro, with the highest effects observed at 0.5 mg L⁻¹ concentration.

This study suggests that holes found in mature hair fibers may be linked to daily hair care actions and the removal of extractable substances.

This article reviews the biology of epithelial stem cells and their role in tissue self-renewal, maintenance, and regeneration, and it highlights the clinical implications of understanding their signaling pathways, but it presents no new clinical findings.
