23 Jul Human corneal limbal stem cell tissue engineering product nourished by fibroblast and preparing process thereof
Abstract
A human corneal limbal stem cell-amnion tissue engineering complex using human corneal limbal fibroblasts as the trophoblast is characterized in that: it is close to the human corneal epithelium form in histology form, and is analogous to the human corneal epithelium in immunology phenotype, its ultrastructure shows that the connection between the cells grows mature and the connection between the epithelia and the amnion carrier is a close conglutination. The culture method includes the following steps: (1) preparing the amnion for culturing the human corneal limbal stem cell in vitro; (2) preparing the human corneal limbal fibroblast trophoblast; (3) preparing the human corneal epithelia suspension; (4) culturing the human corneal limbal stem cell-amnion complex. The human corneal limbal stem cell-amnion complex has analogous phenotype to the human corneal epithelium, and provides a safe and effective biology tissue engineering product to treat corneal limbal stem cell defective eye diseases.
