Adult hair follicle cells can create new hair follicles from corneal cells with the right support.

This study found that ectopic expression of the lymphoid-enhancer factor can induce K17 protein in the skin, suggesting a link between skin development and wound repair processes in mice.

This study explored the carbohydrate composition of plasma cell membranes in human embryonic epidermis over various gestational ages and found specific patterns that may inform future diagnostic and therapeutic approaches for dermatoses.

This study found that trichocytic cytokeratins, typically found in hair, are also present in nails, filiform papillae of the tongue, and the epithelial reticulum of the thymus.

This study found that Wnt7a protein expression increased after corneal epithelial injury and promoted human corneal epithelium cell proliferation by upregulating fibronectin and enhancing cell adhesion.

In this study, DPC-hTERT cells were shown to induce hair follicle-like structures expressing specific keratin when co-injected with epithelial cells into nude mice.

This article reviews key questions in skin biology, particularly the mechanisms of hair follicle patterning and the role of stem cells in the epidermis, reporting no new results.

This review highlights the roles of key transcription factors and signaling pathways in regulating olfactory epithelium regeneration, discussing recent advances in single-cell and spatial transcriptomics as well as organoid models to enhance understanding of olfactory regeneration mechanisms.

This study found that "early" transit amplifying cells, marked by CD271, are the first keratinocyte stem cell progenitors with distinct features, playing a significant role in early epidermal differentiation and regeneration.

This study observed that Bmi1+ central corneal progenitor cells do not contribute to wound healing in mice, which instead rely on epithelial cell rearrangement and migration to close abrasions.

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 study found that inserting isolated hair follicle units into engineered dermis promoted differentiation and maturation of tissue-engineered skin, maintaining hair follicle morphology and generating skin appendages like sebaceous glands.

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 found that basal keratinocytes in engineered skin substitutes showed a proliferative phenotype and potential for long-term replication, which may enhance wound healing stability.

This review discusses the biological features and clinical applications of epidermal stem cells in wound healing and tissue regeneration, emphasizing the need for further understanding of their mechanisms.

This study found that hair follicle stem cells initially contribute to wound re-epithelialization, but long-lasting epidermal cells are primarily derived from a stem cell population in the isthmus portion of hair follicles.

This study found that overexpression of the calcium sensing receptor in transgenic mice accelerates epidermal differentiation and hair growth, suggesting its role in enhancing calcium signaling and interaction with other pathways.

This article reviews a new method to accurately estimate proliferative and migratory epithelial cell numbers post-wounding but reports no experimental findings; the authors suggest its relevance to skin stem-cell biology research.

This study found that different bovine epithelial tissues express varying types of cytokeratins, with hair follicle and nasolabial gland expressing both acidic and basic types, while others express only one or the other.

This study found that treating skin wounds with a combination of epidermis-derived epithelial-like stem/progenitor cells and platelet-rich plasma improved tissue repair and increased vascularization and elastin content compared to platelet-rich plasma alone.

This study categorizes the human fetal vaginal epithelium into four areas with distinct transcriptomic profiles, aiding potential advancements in vaginal reconstruction and drug delivery.

Early-stage skin substitutes improve wound healing and skin structure.

Porcine skin cells are useful for studying wound healing and cancer.

This article explains the significance of culturing the pilosebaceous unit for studying related diseases and skin epithelial stem cells, but it reports no new findings.

This study found that solid basal cell epitheliomas and the outer root sheath of human hair follicles display nearly identical cytokeratin profiles, suggesting a potential origin connection.

This study describes a method using lentivirus in mouse cells to analyze epithelial-mesenchymal signaling important for hair follicle development, offering a quicker alternative to genetic models.

This study found that hair follicle stem cells from young rats can be induced in vitro to differentiate into corneal epithelium-like cells using homogenate of rabbit corneal limbal stroma.

In this study, researchers found that the expression of laminin, collagen type IV, and fibronectin in fetal human skin begins in hair follicle germs and extends to epidermal cells by 21 weeks gestational age.
