This study identified distinct gene expression programs in keratinocytes responsible for forming hard scales and soft interscale epidermis in chickens, revealing conserved differentiation genes similar to those in human skin.

This study reports that during late embryogenesis and early postnatal development, K79-expressing keratinocytes change and die independently of sebaceous glands to form the hair follicle opening, potentially influencing conditions like ingrown hairs or acne.

Dermoscopy greatly improves melanoma diagnosis and reduces unneeded surgeries.

This case report describes a high school wrestler whose forearm rash was initially misdiagnosed as eczema, later identified as Majocchi's granuloma, and successfully treated with oral antifungal therapy after a biopsy.

This review discusses scaffold materials and properties used in epidermal tissue engineering to promote skin regeneration and reports no new research findings.

Understanding skin structure and development helps diagnose and treat skin disorders.

This study suggests that fish oil, specifically its components EPA and DHA, play a beneficial role in promoting skin health by supporting epidermal growth and reducing proinflammatory cytokines.

This study discusses how different modes of regulated cell death in keratinocytes affect skin stem cell niches, and their role in skin inflammation, injury repair, and cancer, based on findings from human dermatological conditions and experimental mouse models.

This case report discusses dental considerations and management strategies for a 7-year-old girl with Ichthyosis Vulgaris; it presents no new clinical results and suggests early preventive therapies.

This review discusses how the nuclear lamina integrates biochemical and mechanical signals to influence gene expression and skin homeostasis, but reports no new clinical results.

This review discusses the roles and characteristics of skin stem cells, their niches, and signaling pathways in skin maintenance, aging, and cancer, highlighting their potential in therapeutic applications but presenting no new clinical findings.

The dog's hair loss healed on its own without treatment.

This study found that deleting the miRNA processing enzymes Drosha and Dicer from mouse skin epithelial cells disrupted normal hair follicle development and maintenance, leading to follicular degradation and stem cell loss during the growth phase.

This review describes recent advances in using nanoparticles for drug delivery to hair follicles, with potential applications in treating skin diseases such as alopecia and acne, but reports no new findings.

This study found that hair follicles are a significant and efficient pathway for the absorption of topical minoxidil foam in humans, with faster blood detection when follicles are open.

This review discusses the role of keratins in maintaining epidermal structure and function and reports no new results; the authors emphasize the lack of rational therapies for skin disorders linked to keratin mutations.

This study found that nonionic liposomes were the most effective vehicle for delivering reporter genes into the skin of rat pups, compared to other liposome and nonliposome formulations.

This review examines beta-catenin's role in stem cell renewal, lineage selection, and tumor formation in the epidermis and reports no new experimental findings.

In this study, researchers observed that loose anagen hair syndrome is an autosomal dominant disorder characterized by abnormal hair follicle structure and premature keratinization, possibly due to signaling and desmosomal component disturbances.

This review discusses recent advancements in understanding hair follicles, their disorders, and potential therapeutic opportunities, but it reports no new clinical findings.

This study suggests that the keratins found in reptile and bird skin appendages evolved independently from mammalian hair keratins, highlighting convergent evolution in these species.

This review explains the mechanical composition and molecular interactions that determine hair's mechanical properties, without providing any new experimental findings.

This article discusses how the balding scalp's exposure to UV and near-infrared light may accelerate aging, with changes detectable under ultraviolet light; it presents no new clinical findings.

This study found that defective cross-linking in hair cuticles is observable in a minority of mouse hair mutants, suggesting different proteins are involved in cross-linking across cell types.

This article reviews the identification and characterization of soluble proteins in horny tissues such as calluses and psoriatic scales, but reports no new clinical results.

In this study, lecithin-based microparticle formulations of minoxidil showed enhanced skin penetration and comparable hair growth effectiveness to commercial products in mice, while minimizing skin irritation often seen with standard minoxidil solutions.

This article discusses the structures surrounding hair follicles and introduces aspects like follicle groups and the dermal sheath, but it reports no new research findings.

This study found that inhibiting arachidonate 12-lipoxygenase (ALOX12) may enhance hair cuticle maturation by increasing S100A3 protein citrullination and promoting cuticular differentiation in isolated human hair follicles.

This article discusses the complex biological functions and social significance of hair follicles and reports no new research findings, emphasizing their role in health, disease, and a substantial beauty industry.

This study found that conditional deletion of Mof in mice resulted in severe defects in skin development, including compromised epidermal differentiation and hair growth, leading to perinatal lethality.
