Reverse transcription polymerase chain reaction analysis of specific embryonic (octamer-binding transcription factor-4) and adult stem cell markers (Wilms’ tumor antigen 1) of rat derived omentum tissue mesenchymal stem cells and liver cell marker gene expression (albumin, alpha fetoprotein, and Cytokeratin-18) in differentiated mesenchymal stem cells. H₂O negative control for polymerase chain reaction (Lane 1), breast cancer cell line SKbr₃ as negative control for albumin (Lane 2), untreated rat derived omentum tissue mesenchymal stem cells (Lane 3), 16 day differentiated cells (Lane 4), 18 day differentiated cells (Lane 5), 21 day differentiated cells (Lane 6), cell line HepG₂ as positive control (Lane7)
