Corneal keratocytes in vitro make collagen

WebNov 16, 2024 · Presently, research has focused primarily on the production of collagen-based or inspired corneal implants that promote regeneration. The most common collagens are type I and III in the form of hydrogels, which have already been evaluated in clinical trials. In vitro tests of collagen sponges are also in progress [134,135,136]. WebCorneal keratocan plays a pivotal role in matrix assembly, which is essential for corneal transparency. Keratocan-null mice have thinner corneal stromas with larger collagen fibril diameters and less organized fibril packing, compared to their wild-type counterparts. In addition, the corneas have an altered shape with narrower corneairis angles.
