本组共收集２６份脐带血、１８份骨髓、２２份外周血，用琼脂半固体培养法，培养粒单系造血祖细胞（ＣＦＵ－ＧＭ）。结果表明，脐带血ＣＦＵ－ＧＭ的平均产率接近骨髓，明显高于成人外周血。脐带血富含造血祖细胞，既可作为造血干细胞移植新的来源，又可用于骨髓抑制患者的临床输注，有广阔的应用前景。
The group collected a total of 26 umbilical cord blood, 18 bone marrow and 22 peripheral blood mononuclear hematopoietic progenitor cells (CFU-GM) cultured with agar semi-solid culture. The results showed that the average yield of umbilical cord blood CFU-GM close to the bone marrow, significantly higher than adult peripheral blood. Umbilical cord blood is rich in hematopoietic progenitor cells, both as a new source of hematopoietic stem cell transplantation, but also for the clinical infusion of bone marrow suppression patients, has broad application prospects.
