They play a key role in maintaining the structure and transparency of the cornea, as they are the source of stromal collagen and proglycans. They also play important roles in corneal wound healing and tissue repair, and are known to undergo phenotypic transformations in wounds due to the influence of growth factors and cytokines [1]. Under normal conditions, the keratocytes in the adult cornea are relatively quiescent cells. In the event of corneal injury or trauma, however, the keratocytes differentiate into active, synthesizing cells and rapidly replace damaged stromal matrix. Cultured human keratocytes express functional IL-4Rs [2] and IL-17R [3] on the cell surface, suggesting that these cells may contribute to the role of IL-4 and IL-17 as mediators of allergic reactions in the cornea. Changes in gene expression were observed in keratocytes after interleukin-1 treatment, which provides important insight into gene expression and suggests novel therapeutic targets for the control of corneal inflammation.<\/p>\n<p>iXCells Biotechnologies provides high quality Rat Keratocytes (RK), which are isolated from neonate day 2 rat cornea and cryopreserved at P1, with &gt;0.5 million cells in each vial. RK are characterized by fibroblast morphology.
