To investigate expression of the NOGO-A gene and its receptors in human amniotic fluid (HAF)-treated human retinal pigment epithelial (hRPE) cells compared to fetal bovine serum (FBS)-treated cells.
Gene expressions of NOGO-A and its receptors, NgR1 and lingo-1 were investigated and analyzed in 30% HAF- versus FBS-treated hRPE cells by using real time PCR.
Our results showed that NOGO-A, NgR1 and Lingo-1 are normally expressed in hRPE cells. Gene expressions of NOGO-A, NgR1, and Lingo-1 in HAF-treated hRPE cells were 112 (P < 0.001), 20 (P < 0.001), and 11 (P = 0.014) times higher as compared to values in FBS-treated cells, respectively.
Increased gene expression of NOGO-A and its receptors support neural differentiation of hRPE cells in the presence of HAF. Our findings provide further evidence on the effectiveness of HAF in trans-differentiation of hRPE cells into neural progenitors and retinal neural cells, which may be of significance in cell replacement therapy.
