In this video, we show a procedure to obtain ocular pigment epithelial cells from a rabbit model. The cells are helpful in developing therapeutic strategies for retinal degenerative diseases.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. New Zealand white rabbits were euthanized by an overdose of Pentobarbital (150 mg/kg) diluted in 0.9% NaCl injected intraperitoneal and the eyes were enucleated immediately after sacrifice. 1. Before preparation Prepare complete medium (DMEM/Ham's F12 supplemented with 10% fetal bovine serum (FBS), 80 U/mL p…
