Abstract
Recent studies suggested that placentae amniotic membrane is a valuable source of stem cells in human as well as in livestock species. Advantages of amnion over other sources of stem cells included abundant availability, ethically non-objectionable and non-invasive source. The aim of the present study was the isolation, culture and characterization of amniotic-membrane-derived mesenchymal stem cells from term placentae collected postpartum in buffalo. We have observed that both presumptive epithelial-like and fibroblast-like cells were cultured and maintained from term amnion. These cells were shown the positive expression of pluripotency markers (OCT-4, SOX-2, NANOG, TERT), mesenchymal stem cell markers (CD29, CD44, CD105) and negative for haematopoietic marker (CD34) genes at different passages. In addition, these cells were also positive for alkaline phosphatase staining. Stem-ness potential of any stem cells is determined by their potential to differentiate into specific lineages of cell type. In the present study, we have successfully differentiated the amniotic-membrane-derived cells into adipogenic, chondrogenic and osteogenic lineages of cells in vitro. In conclusion, the results of this study demonstrate that amniotic-membrane-derived cells expressed pluripotent and mesenchymal stem cells markers and have propensity to differentiate into cells of mesenchymal lineage cell type upon directed differentiation in vitro.
