Abstract

In this video we describe a technique to isolate iris and retinal pigment epithelial cells from porcine eyes to obtain their primary cultures for in vivo and ex vivo studies. These pigment cells could be genetically modified to study regenerative approaches to treat ocular disorders.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Before preparation Prepare complete medium (DMEM/Ham's F12 supplemented with 10% fetal bovine serum (FBS), 80 U/mL penicillin / 80 µg/mL streptomycin, and 2.5 µg/mL amphotericin B). Heat the medium, 1x PBS, and 0.25% trypsin (if necessary) in a 37 °C water bath. Put a sterile drape into the …
