Abstract
OBJECTIVE: To establish a cell line and purification model of retinal ganglion cells (RGCs) in vitro. METHOD: RGCs from Sprague Dawley neonatal rats (postnatal 1 - 3 days) were cultured in basal medium eagle (BME) basal medium. The growth regularity of RGCs in vitro was observed under phase-contrast microscope. RGCs were purified by Thy 1.1 with FITC antibody and detected under fluorescent microscope and phase-contrast microscope. RESULTS: Higher density of retinal cells and tectal extract facilitate cultured RGCs to survive. The purification rate of retinal ganglion cells in the experiment arrived at 95 percent. CONCLUSION: Cytokine and trophic factors from other cells in the retina and tectal extract can promote RGCs to survive, and they can be purified by Thy 1.1 antibody.
