OBJECTIVE We hypothesize that the pathogen-free NIKS human keratinocyte progenitor cell line cultured in a chimeric fashion with patient's primary keratinocytes would produce a fully stratified engineered skin substitute tissue and serve to deliver autologous keratinocytes to a cutaneous wound. SUMMARY OF BACKGROUND DATA Chimeric autologous/allogeneic bioengineered skin substitutes offer an i...
We have compared the adhesive properties and integrin expression profiles of cultured human epidermal keratinocytes and a strain of nondifferentiating keratinocytes (ndk). Both cell types adhered to fibronectin, laminin, and collagen types I and IV, but ndk adhered more rapidly and at lower coating concentrations of the proteins. Antibody blocking experiments showed that adhesion of both cell t...
Delineating the factors that orchestrate keratinocyte growth and differentiation in the claw is pivotal to understanding the quality of hoof horn production in health and disease. The specific objectives of this investigation were to establish an in vitro culture system for bovine coronary region keratinocytes and dermal fibroblasts, determine the colony-forming capacity of epidermal keratinocy...
Cells of the human embryonic stem (hES) cell line H9, when cultured in the form of embryoid bodies, give rise to cells with markers of the keratinocyte of stratified squamous epithelia. Keratinocytes also form in nodules produced in scid mice by injected H9 cells; the hES-derived keratinocytes could be recovered in culture, where their colonies underwent a peculiar form of fragmentation. Whethe...
BACKGROUND Accumulating evidence has demonstrated that migration of keratinocytes is critical to wound epithelialization, and defects of this function result in chronic delayed-healing wounds in diabetes mellitus patients, and the migration has been proved to be associated with volume-activated chloride channels. The aim of the study is to investigate the effects of high glucose (HG, 25 mM) on ...
Keratinocytes freshly isolated from unwounded skin could not attach and spread on fibronectin (FN)-coated culture dishes and could not bind and phagocytose FN-coated beads. These adhesive functions were activated, however, in keratinocytes that were isolated from healing wounds. Moreover, adhesiveness of basal keratinocytes to FN substrata was activated during epidermal cell or explant culture....
Background: Psoriasis is a chronic inflammatory dermatosis. The hyperproliferation and hyperkeratosis of keratinocytes key step in the pathogenesis psoriasis. Long non-coding RNAs (lncRNAs) mRNAs regulate gene expression various biological process, including function keratinocytes. This research investigated profile lncRNAs patients with psoriasis vulgaris.
Keratinocytes from involved psoriatic plaques (PP), uninvolved, clinically symptomless skin of psoriatic patients (PN) and normal healthy skin (NN) have been cultured in a low calcium serum free system for multiple passages. In this way, the keratinocytes were removed from microenvironmental factors present in the skin. While the basal rate of proliferation of the PP, PN and NN keratinocytes wa...
Vitiligo is an acquired depigmentary skin inflammatory disorder. The pathogenesis of inflammatory skin disease involves the release of cytokines from keratinocytes, including interleukin (IL)-1β. IL-22 belongs to a family of cytokines structurally related to IL-10, including IL-19, IL-20, IL-24, and IL-26. In contrast to IL-10, IL-22 has proinflammatory activities. Among skin cell populations o...
The multistage evolution of squamous skin tumors induced by chemical or viral carcinogens on mice from different genetic backgrounds has been a valuable model to define low penetrance loci that determine cancer susceptibility or resistance. Susceptibility determinants are multigenic, stage-specific, dependent on the carcinogenesis protocol, and in the case of initiating events, intrinsic proper...
