Multipotent mesenchymal stromal cells of placental origin are used to treat critical limb ischemia, dilated cardiomyopathy, and hematopoiesis recovery after transplantation of hematopoietic stem cells. Therefore development of the methods of placental tissue cryopreservation and isolation of placental-derived multipotent mesenchymal stromal cells and the study of their molecular-biological properties and capacity to multilineage differentiation and regenerative potential is an actual task. It was shown that multipotent mesenchymal stromal cells excreted from native and cryopreserved human placenta tissue had similar morphology, immunophenotype and multilineage differentiation capacity. For the first time, it was established that placental multipotent mesenchymal stromal cells expressed mesenchymal and epithelial cells markers, contained of cytokeratin 7-positive cells that expressed vimentin and CD90. We isolated the cells that migrated from the placental tissue during culturing in cell culture medium with human serum that were similar in immunophenotype to the multipotent mesenchymal stromal cells. These multipotent mesenchymal stromal cells, isolated from native and cryopreserved placental, were able to survive homing and integrating into damage cardiac tissue of mice in vivo.
Key words: placenta, multipotent mesenchymal stromal cells, cryopreservation, cardiomyopathy, myocardium.
