WebApr 13, 2024 · During corneal wound healing, corneal keratocytes are exposed to both biophysical and soluble cues that cause them to transform from a quiescent state to a repair phenotype. How keratocytes integrate these multiple cues simultaneously is not well understood. To investigate this process, primary rabbit corneal keratocytes were … WebCorneal keratocytes. Keratocytes are flattened cells found dispersed within the corneal stroma. The primary role of this sparse population of cells is thought to be in maintaining the extracellular matrix of collagen …
WebAbstract. PURPOSE: TGFbeta is the major mediator to induce myofibroblast differentiation in the corneal wound-healing process. Elevated cAMP can reduce TGFbeta-induced fibrosis in other tissues. This study was conducted to determine whether elevated cAMP can inhibit TGFbeta1-induced rabbit corneal keratocyte-myofibroblast transformation. WebAlterations in keratocyte biosynthetic activity, regardless of their cause, ultimately lead to fibrillar alterations responsible for a loss of corneal transparency. Keratocytes are differentiated mesenchymal fibroblast which are specialized in the production and maintenance of the transparent corneal stroma. These elongated cells with large nuclei …
WebThe corneal stroma is a mesenchymal connective tissue making up 90% of the corneal thickness, with physical properties that provide the cornea its essential character.
