To observe the role of all-trans retinoic acid (ATRA) during the similar myopia changes of cultured rabbit retinal pigment epithelium (RPE) cells, as well as the variation changes and relationships with myopic correlation factors such as hepatocyte growth factor (HGF) and matrix metalloprateinase-2 (MMP-2). Rabbit RPE cells of primary generation were selected and cultured to fifth generation by subculture. Then the morphology of RPE cells were observed and cell vitality was analyzed by using the Trypan blue reject test. The expressions of HGF and MMP-2 in RPE cells were tested by using an immunobistochemistry method. The HGF concentration in RPE cell culture fluid was detected by applying enzyme-linked immunosorbnent assay (ELISA). As the ATRA concentration enhanced and action time prolonged, the survival rate of RPE cells was reduced, but the expressions of HGF and MMP-2 increased, so did the secretion of HGF. ATRA concentration with no less than 5 nM/ml was able to induce the growth inhibition of RPE cells and the decrease in survival rate, which was similar to the changes in RPE cells in myopia. With the actin of ATRA, the expressions of HGF and MMP-2 increased in RPE cells, with more distinct in HGF increase.
