Method for efficiently separating and expanding mesenchymal stem cells in human umbilical cord blood

The invention relates to an optimal method for efficiently separating and expanding mesenchymal stem cells in umbilical cord blood in cell therapy. The fact that the mesenchymal stem cells with higher differentiative capacity and smaller immunological rejection are contained in the umbilical cord blood has been proved. The establishment of an umbilical cord blood bank provides a basis for achieving transplantation of autologous cells. However, since the content of the mesenchymal stem cells in the umbilical cord blood is very low (only 0.5 to 30 mesenchymal stem cells are contained in 1*108 mononuclear cells), how to efficiently separate and expand the mesenchymal stem cells becomes a problem hindering the transformation of the mesenchymal stem cells in the umbilical cord blood to the clinical application. At present, in most situations, the mesenchymal stem cells in the umbilical cord blood are separated in virtue of adsorption capacity of the mesenchymal stem cells in a culture vessel, but the success ratio is low, and the characteristics of stem cells are difficult to maintain in an expanding process. The method comprises the steps of coating the culture vessel with protein components, adding multiple growth factors in the culture vessel in a coordination manner, and building the expansion environment of the mesenchymal stem cells in the umbilical cord blood, so as to achieve the efficient separation and expansion of the mesenchymal stem cells.
