Extracellular matrix in the healthy cornea
A major focus in our laboratory is understanding the structure and functions of the cells and the ECM of the cornea. The transparent cornea provides two thirds of the refractive power of the eye and serves as a protective barrier through unique adaptations of the cells and the ECM. The stromal ECM connective tissue is a highly organized array of collagen fibrils and regulatory proteoglycans produced by a specialized fibroblast, the keratocytes. We are trying to understand properties of keratocytes, their development and whether they can be maintained in culture to produce a cornea-like stromal ECM.
