近年来,利用骨髓细胞、胎肝细胞、外周血单个核细胞治疗造血障碍性疾病是引人注目的研究动向,也是治疗极重度放射病包括肠型放射病的可能有效措施。它们有效成分是造血干细胞。就造血干细胞的来源来看,在外周血中的造血干细胞数量虽少,但分离浓集比较方便,也容易为人们所接受。关于外周血干细胞的测试技术,对各种动物都已有报道,但对狗 In recent years, the use of bone marrow cells, fetal liver cells, peripheral blood mononuclear cells in the treatment of hematopoietic disorders is an interesting research trend, but also the treatment of very severe radiation sickness, including enteropathy may be effective measures. The active ingredient is hematopoietic stem cells. In terms of the origin of hematopoietic stem cells, although the number of hematopoietic stem cells in the peripheral blood is small, it is easy to separate and concentrate, which is also easily accepted by people. Testing techniques for peripheral blood stem cells have been reported for a variety of animals, but for dogs
