Culture and identification of pig retinal pigment epithelial cells in vitro / 中国医师杂志

ABSTRACT

Objective In order to provide a large quantity of retinal pigment epithelial cells (RPE cells) in vitro, we want to estab-lish method for culturing pig RPE cells. Methods RPE cells were separated with trypsin and cultured in vitro. The cells were identified by immunohistochemical staining with anti-human keratin and transmission electron microscope (TEM). Results Cultured RPE cells gradually presented transparent and fusiform shape. Immunohistochemical staining demonstrated that the cells were stained by anti-human keratin, and the cultured cells showed typical ultrastructure of RPE cells. Conclusion The cultured cells may be the foundation of pig RPE cells.
