Keratinocytes might turn into stem cells, but more research is needed to confirm this.

This study demonstrated that keratin is widely present in various epithelial cells, providing structural strength and potential insights into the origin of cell lines.

This study identified ectomesenchyme as a major source of epidermal stem cells in mouse skin, with ectomesenchymal keratinocytes occupying a significant portion of the epidermal stem cell-enriched population.

This study found that incorporating dermal papillae cells and keratinocytes into dermal substitutes promoted better wound healing, reduced contraction, and enabled appendage formation in tissue-engineered skin on mice.

This study found that dendritic epidermal T cells and their exosomes enhance epidermal stem cell proliferation, accelerating wound re-epithelialization in the skin.

This review discusses the role and plasticity of epidermal stem cells in skin maintenance, wound repair, and cancer, noting recent insights from advanced technologies but providing no new clinical results.

This article reviews the role of epithelial-mesenchymal interactions in hair follicle development and discusses the challenges of understanding the signals that regulate this complex process; it reports no new results.

This study describes the structure and composition of the epidermal horny layer in elephant seals, noting that its keratinized cells are attached without a specialized fission zone, differing from the sloughing mechanism in reptiles.

Balanced protease activity is crucial for healthy skin and hair development.

Eye lens capsules are the best for growing human skin cells.

This study found that in superficial angiomyxomas, S100A4-positive mesenchymal niches may induce non-neoplastic adnexal epithelial growth, and highlighted evidence of mesenchymal-to-epithelial transition in eccrine duct branching, especially in Carney's complex cases.

This study showed that coexpression of TG2 and Gbx1 in the epidermis is necessary for esophagus-like mucosal transdifferentiation, with TGF-beta2 in the dermis essential for the process through epithelial-mesenchymal interaction.

This study demonstrated the potential of epithelial cell scaffolds fabricated with various materials for effective hair regeneration, highlighting their promising application in tissue engineering for alopecia treatment.

This review examines the differentiation potential of epithelial cells from various sources in hair follicle formation, concluding that complex interactions are required for hair-specific characteristics, which were achieved in vivo but not in vitro.

This article reviews the role of epithelial-mesenchymal interactions in hair follicle morphogenesis and the hair cycle, suggesting potential paths for developing treatments for hair growth disorders but providing no new clinical findings.

This study found that poly(ethylene-co-vinyl alcohol) membranes support the self-assembly of dermal papilla cells into compact spheroidal microtissues capable of inducing new hair follicles, suggesting potential for large-scale production for hair follicle regeneration.

This study reported that human induced pluripotent stem cell-derived skin organoids, used to model epidermolysis bullosa, have an epidermal-dermal junction largely lacking type VII collagen, which is important for skin structure.

This study observed that cell aggregates formed rapidly in cultures of rat hair follicle cells, with proteins showing hair cortical keratin but not synthesizing it as anticipated.

This paper reviews recent findings on epidermal development and stem cell regulation, listing key studies that contribute to understanding the molecular pathways involved in skin morphogenesis without reporting new experimental results.
