Different keratin proteins are expressed in various epithelial cells at different stages, affecting cell structure and function.

This study demonstrates that α-parvin is crucial for epidermal morphogenesis and hair follicle development by mediating integrin-dependent adhesion and actin organization in keratinocytes.

In this study, expressing human K16 in the epidermis of K14 null mice prevented early skin blistering but led to age-related anomalies, indicating K16 and K14 have distinct roles despite their sequence similarity.

This article reviews keratosis follicularis squamosa, a keratinizing disorder predominantly found in the Japanese population, but reports no new clinical results.

This review discusses the reuse of molecular mechanisms involved in embryonic skin development for maintaining adult epidermal homeostasis and reports no new results.

Minoxidil promotes hair growth by increasing cell division and DNA synthesis.

This review discusses the potential markers for identifying and studying stem cells in the epidermis and hair follicles, highlighting their role in understanding skin disease pathogenesis and expanding therapeutic options, but reports no new findings.

This review discusses how epidermal Langerhan's cells and dermal cells may influence keratinocyte environments, potentially aiding in the formation of stem cell niches and cellular variety in the basal layer, without providing novel results.

This study found that the subtilisin protease Sub3 from Microsporum canis is essential for adherence to the feline epidermis but is not necessary for invading epidermal structures.

This study found that cold air can effectively preserve the epidermis when using an 810 nm diode laser, but it is slightly less effective than a chilled sapphire window in dark-haired pigmented pigs.

This study found that epidermal stem cells in nonglabrous skin are connected to the distal end of the arrector pili muscle, which may play a role in epidermal renewal and wound healing.

This study found that specialized nipple epidermis in mice is maintained by the repression of TGFβ signaling through estrogen, which highlights the role of hormonal regulation in epidermal maintenance.

This study concluded that a new model of reconstructed human epidermis using keratinocytes from plucked hair follicles offers a less-invasive alternative to conventional skin-derived models for skin research.

In this study, researchers used patient-derived organoids to model metastasis in colorectal cancer and discovered that cancer cells temporarily switch to a wound-healing program, orchestrated by reduced EZH2 activity and YAP signaling, before spreading to new organs.

This study revealed that in androgenic alopecia, the proximal attachment of the arrector pili muscle to the hair follicle is often lost or significantly reduced.

In this study, terbinafine reached high concentrations in stratum corneum and sebum after oral administration, with drug levels remaining above fungicidal concentrations for over three weeks.

This essay discusses the establishment, maintenance, and role of skin stem cells in tissue homeostasis, wound repair, and their relation to skin cancer, without reporting new experimental findings.

The skin protects the body, regulates temperature, senses touch, and makes vitamin D.

This article reviews advancements in understanding skin regeneration and suggests that bioengineering skin surrogates may soon enhance treatments for skin trauma, but it presents no new clinical findings.

This study found that actomyosin contractility in suprabasal keratinocytes influences the proliferation and differentiation of epidermal stem/progenitor cells by acting as a niche element in the skin.

The document concludes that secondary syphilis cases are increasing and often misdiagnosed, pityriasis rubra pilaris can be distinguished from psoriasis by skin cell features, and different skin layers produce specific components during skin repair.

This article discusses the coordinated roles of different epidermal stem cells and other cell types in the skin's wound healing process and reports no new experimental results.

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.

This article explains the structure and multifunctional roles of the human skin, including its protective, regulatory, and sensory functions, but does not report new research findings.

This study demonstrates that exfoliative cutaneous lupus erythematosus in German short-haired pointers involves a cellular and humoral immune response against the epidermal basement membrane, with poor response to immunosuppressive therapy.

This review discusses changes in keratin structure or gene expression that result in various skin disorders and reports no new clinical findings.

This study found that disrupting Lm332 expression in mice changes keratinocyte genetic expression, alters cell shape, and disrupts epidermal homeostasis, despite some compensatory anchorage by hair follicle basal cells.

This study mapped gene expression in different skin structures of dogs, finding similarities to humans that support using dogs as models for human skin diseases.

This review discusses the formation and structure of the cornified cell envelope in the epidermis, highlighting biochemical pathways and genetic factors, but presents no new experimental results.

This study demonstrates that stem cells from human foreskins, which lack hair follicles, can differentiate into melanocytes and migrate to the epidermis, potentially altering our understanding of pigmentation disorders.
