Figure 4. Phase appearance and marker protein expression of cultivated corneal limbal epithelial cells, keratocytes, and endothelial cells. The rabbit corneal limbal epithelial cells (A), keratocytes (B), and endothelial cells (C) were cultivated for one week to confluence on culture dishes, primary (10X). The protein of keratin 3 was specially expressed in the cultivated corneal limbal epithelial cells while vimentin expression was highest in the keratocytes. Aquaporin A was only detected in the endothelium (D).
