OBJECTIVE To observe the effect of Lycium barbarum polysaccharide (LBP) on rat retinal ganglion cells (RGCs) in vitro. METHODS Retinal cells of neonatal Sprague-Dawley rats were collected 1 to 3 days after birth, and co-cultured with different concentrations of LBP for 24 hours. Absorbance values (OD) were recorded using MTT assay for calculating survival rates. RESULTS All the test groups had protective effects on RGCs. The group with 10mg/mL concentration of LBP had the most significantly difference of OD value compared with that in control group (P<0.01). CONCLUSIONS LBP can increase the survival rate and promote the growth of mixed cultured rat RGCs.
