Figure 8. Protective effect of cassia polysaccharide on the proliferation ability of ARPE-19 cells after inhibition by PAX6-shRNA lentiviral vector. The results of CCK-8 assay showed that cassia polysaccharide exerted a certain proliferation-promoting effect on cells after PAX6 knockdown. Data were expressed as mean ± standard deviation (SD); (n=3; *p<0.05, **p<0.01 versus the control group).
