Purpose of study: Neurosphere-free trans-differentiation of bone marrow stem cells (NFT-BMSCs) into retinal pigment epithelium (RPE) and retinal cells (RCs) in vitro could offer a unique opportunity for the study of cell-replacement in degenerative eye diseases. In this respect, a simple, and efficient protocol for getting retinal cells from trans-differentiation of rat BMSCs in the neurosphere-free state are reported. Methods: Extracted BMSCs from hooded pigment rats were exposed to a single-step protocol, including neurosphere-free, containing a cocktail medium which induced trans-differentiation into retinal pigment epithelium (RPE) and retinal cells. Results: The results showed morphological differentiation changes in vitro. Also, expressed retinal pigment epithelium and retinal cell markers such as Otx2 (23.45%), RPE65 (91.54%), CRALBP (91.21%), VEGF (94.79%), Rhodopsin (57.19%), GFAP (28.33%), and NF200 (24.55%). Conclusion: Overall, these findings showed a protocol, without using bFGF, EGF, and B-27 supplement which makes it possible to obtain RPE and retinal cells in vitro.
