Figure 1. The MER proto-oncogene and the Mertk gene expression ratio between BM-MSCs and RPE cells at different passages and among different passages of BM-MSCs. The first three columns show the ratio of bone marrow mesenchymal stem cells (BM-MSCs) versus RPE cells. The last two columns show the ratio among different passages of BM-MSCs. The asterisk (*) represents p<0.05. The sampling size for each group is 3.The error bars are standard deviation (SD). The data were analyzed with one-way ANOVA. The Mertk gene expression of BM-MSCs was significant greater than RPE cells at P0 and P1.
