Figure 5. Effects of recombinant N-SLIT2 protein on human retinal pigment epithelium cell proliferation. Retinal pigment epithelium (RPE) cell proliferation was measured using an MTT assay at 24 h. Values reported are mean±SD from three independent experiments. Asterisks denote values significantly different from those of cells treated with recombinant N-SLIT2 protein compared to control cells (p<0.05).
