This study found that treating reconstructed human epidermis with beta-lipohydroxy salicylic acid increased tight junction remnants in the stratum corneum, potentially affecting skin cohesion and desquamation.

The researchers reported that in hairless mice, epidermal cell division orientations and epidermal thickness varied by body site, with dorsal and ear epidermis primarily dividing parallel to the basement membrane, unlike hind paw and tail epidermis.

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 constructed a comprehensive atlas of prenatal human skin, revealing that innate immune cells, such as macrophages, play a crucial role in skin morphogenesis by interacting with non-immune cells, influencing hair follicle formation and angiogenesis beyond their traditional immune functions.

This study observed that the expression of EGF and EGFR increased during goat fetal skin development, suggesting these components play significant roles in skin maturation.

This review discusses the development and types of hair and nails as skin appendages and reports no new research findings.

This study mapped the development of the human pilosebaceous unit in prenatal scalp skin using multi-modal analysis, finding that epithelial-mesenchymal interactions guide cellular fate and validated tissue-patterning through a hair-bearing skin organoid model.

This study reviews the complex keratinization process in the epidermis, detailing how various factors regulate keratinocyte differentiation and emphasizing the importance of understanding this process for the pathogenesis of skin disorders like ichthyoses and psoriasis.

This study found that the Florida worm lizard has lost certain genes associated with claw development, which are present in other lizard species with claws, suggesting a link between the evolution of their limbless body and the loss of claw-related genes.

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 case report describes a preterm newborn with lamellar ichthyosis, detailing management with acitretin, vitamin D, and emollients, and emphasizes the importance of regular monitoring due to potential adverse effects of long-term retinoid therapy.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.

This study found that specific genetic changes in both coding and noncoding regions may have independently driven the evolution of hairlessness in various mammalian species through accelerated evolution.

In vitro skin models are improving but still need more innovation to fully replicate human skin.

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

This study suggests that fibroblast growth factors exhibit significant expression differences in rodent and primate skin, potentially related to their evolutionary paths and environmental adaptations.

This study suggests that both age and photoexposure may decrease maximum viable epidermis thickness and impact the dermal-epidermal junction in women with Fitzpatrick skin types II-III.

This review discusses the advancements and challenges in developing in vitro human skin models incorporating components like vasculature for drug testing and disease research, but reports no new clinical results.

In this study, mouse amnion epithelium was successfully transformed into skin and hair follicles when associated with hair-forming dermis, revealing the necessity of specific influences for follicle formation.

This study suggests that human outer root sheath cells are suitable for skin replacement, as they can form a stratified epithelium similar to normal epidermis in organotypic cultures.

This review discusses the regeneration capabilities of various vertebrate tissues, focusing on the unique ability of certain species to regenerate teeth and lens, and reports no new results.

Research on epidermal stem cells has advanced significantly, showing promise for improved clinical therapies.

This study reports that immunologically inert and skewed immune cell populations in developing human skin may contribute to wound healing and structural changes during skin development.

Cell movements and forces shape feather growth in chicken skin.

This study found that by using an automated system to analyze skin histology, 108 structural features were significantly affected by age, and it identified four new aging biomarkers and notable sex-based differences in skin aging.
