Abstract

The invention provides a human marrow, umbilical cord blood and peripheral blood stem cell isolation kit and an isolation method thereof. The isolation kit comprises a reagent A, a reagent B and a reagent C, wherein the reagent A is sodium chloride solution, the reagent B is sodium chloride solution with hydroxyethyl starch and a mixed antibody, and the reagent C is iodixanol operating fluid or lymphocyte separating medium. In the reagent B, a mass concentration of the hydroxyethyl starch is 5-10%, and a concentration of the mixed antibody is 4-12microgram / ml. The isolation method is characterized in that a negative selection collection method is adopted for selectively removing red blood cells, blood platelets, all plasma substances, mature blood cells and lymphocytes; all lin negative stem / progenitor cells can be collected; adoption of a mobilizing agent and plasma residuals are avoided; high-capacity isolation of marrow, umbilical cord blood and peripheral blood can be realized, and cell recovery rate reaches 85%. The isolation kit and the isolation method are especially suitable for treatment of marrow, umbilical cord blood and peripheral blood samples extracted clinically and in umbilical cord blood banks.

Description

technical field

[0001] The present invention relates to a human bone marrow, umbilical cord blood and peripheral blood stem cell separation kit and a separation method thereof, in particular to a kit for rapidly separating large-capacity human bone marrow, umbilical cord blood and peripheral blood stem cells made by using the negative selection method principle, It is composed of diluent, separation liquid and washing liquid to meet the needs of clinical stem cell therapy. Background technique

[0002] As 2007 came to the end of the year, the life science field was surging again. Two research groups in Japan and the United States successively used transgenic technology to introduce Oct4, nanog, sox2 and other genes into ordinary human fibroblasts, and found that the reprogramming of fibroblasts possessed the characteristics of human embryonic stem cells. The results of this research caused a shock all over the world. The U.S. government has made persistent efforts and inve...
