This study found that Polyomavirus A2 infection in mice led to the development of pilomatricomas in hair follicles, with the virus replicating initially in the skin and later infecting matrix cells.

In this study, researchers found that the EDMTFH protein is present in specific layers of the chicken embryo skin and feathers, suggesting its role in feather mechanics and development.

This review examines the role of stem cells and their niches in continuously growing ectodermal organs like teeth, hair, and claws, providing insights from mouse models without presenting new research findings.

This study discusses the epithelial-immune microenvironment in chronic skin diseases, such as psoriasis and atopic dermatitis, and highlights current and future treatment strategies targeting inflammatory loops within these diseases.

This study found that combining optical clearing methods with light-sheet fluorescence microscopy allows detailed 3D visualization of normal and pathological human skin biopsies, revealing differences in epidermal thickness and volume.

This study found that CD99 is strongly expressed in the basal cells and hair follicles of normal adult and developing fetal skin, with expression patterns becoming similar after 20 weeks of gestation.

This study found that two microRNAs, oar-miR-23b and oar-miR-133, inhibit the development of hair follicles in superfine wool sheep by targeting genes involved in key signaling pathways, suggesting their potential use as molecular markers for breeding fine wool sheep.

This study found that their novel 3D-imaging method, ASAXA-μCT, identified shrinkage of sweat glands as a key factor in skin aging, which leads to dermal defects, decreased elasticity, and increased wrinkling and sagging.

This study found that ocu-miR-205 influences hair follicle density and signaling pathways in Rex rabbits by promoting dermal papilla cell apoptosis and altering hair follicle phases.

In this study, researchers developed a model using iPS-derived cells to trace and evaluate hair follicle differentiation, which could aid in the development of hair growth treatments.

In this study, transiently activating the sonic hedgehog signaling pathway in chickens transformed reticulate scales on the feet into feathers comparable to body feathers, without ongoing treatment, suggesting this pathway affects the diversity of bird skin appendages.

This study found that vitamin D supplementation in diets of Rex rabbits improved hair follicle development and fatty acid metabolism, with 1400–2100 IU/kg proving most effective for hair density and 2800 IU/kg increasing hair length.

This study found that bioelectric and biochemical signaling mechanisms coordinate collective cell movement during chicken feather bud morphogenesis, suggesting a potential new angle for research in skin development and wound healing.

This study found distinct gene expression profiles in the parietal and occipital scalp of individuals with androgenetic alopecia, linked to developmental origins and susceptibility to hair loss, offering insights into genetic and epigenetic factors involved in AGA.
