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.

The invention discloses an injectable articular cartilage tissue repair material and is characterized in that starting materials of the composite material contain the following components of: by weight, 100 parts of I-type collagen and 10-50 parts of hyaluronic acid, wherein oxidisability of hyaluronic acid is 20-60%. A monocyte layer in bone marrow fluid in vivo is embedded in the repair material. The thickness of the composite material is 1-5mm. Hyaluronic acid is oxidized into oxidized hyaluronic acid by the use of sodium periodate. The collagen solution, 5*PBS and a buffer are mixed at the volume ratio of 7:2:1 and the pH is adjusted to neutral. After dissolving oxidized hyaluronic acid by the use of ultrapure water, the dissolved oxidized hyaluronic acid is added into the neutral collagen solution and the mixed solution is uniformly stirred and stands in a refrigerator of 4 DEG C. The separated and extracted monocyte layer in the bone marrow fluid by a density gradient centrifugation method is uniformly mixed with the above collagen-oxidized hyaluronic acid solution. The mixed liquor is putted into a constant temperature incubator of 37 DEG C for standing or injection to the organism articular cartilage defects so as to form the composite material.
