Abstract:

BACKGROUND: High-dose chemotherapy often results in severe bone marrow damage. Beside medicines, stem cells transplantation has also been as a strategy for the treatment of bone marrow damage.
OBJECTIVE: To investigate the effects of human amnion-derived mesenchymal stem cells transplantation on the hematopoietic function of myelosuppression mice induced by cisplatin.
METHODS: Human amnion-derived mesenchymal stem cells were cultured in vitro. The female Imprinting Control Region mice were divided into three groups. Excepted for the mice in the blank group, the mice in the other groups were intraperitoneal injected with cisplatin to make the myelosuppression Imprinting Control Region mice, then the 3.0×105/g human amnion-derived mesenchymal stem cells were injected into the mice in the human amnion-derived mesenchymal stem cells transplantation group through the caudal vein, and PBS solution in the same dose was injected in the mice of blank group and model group.
RESULTS AND CONCLUSION: On day 7, the body weight of Imprinting Control Region mice was reduced after administrated with cisplatin for 7 days, there was no significant difference between model group and human amnion-derived mesenchymal stem cells transplantation group. The number of white blood cells, lymphocytes,mononuclear cells, red blood cells, hemoglobin, hematocrit and platelet of peripheral blood in the model group were significantly lower than those in the blank group (P < 0.05), then the indexes above began to recover on day 21 after cisplatin treatment. The recovery of the indexes above of the peripheral blood in the human amnion-derived mesenchymal stem cells transplantation group was 7 days earlier than that in the model group, and the indexes above were recovered to normal level at 21 days; compared with blank group, the number of white blood cells and platelet in the human amnion-derived mesenchymal stem cells transplantation group was transiently increased at 1-2 days before transplantation and 2 days after transplantation. At 24 days after transplantation, the number of bone marrow karyocytes in human amnion-derived mesenchymal stem cells transplantation group was significantly higher than that in the model group (P < 0.05). Bone marrow histopathological testing results showed that the mice femur bone marrow organizational structure in the human amnion-derived mesenchymal stem cells transplantation group was significantly improved. Compared with blank group, the number of bone marrow nucleated cells, especially megakaryocytes, was higher in human amnion-derived mesenchymal stem cells transplantation group, and at 2 weeks after human amnion-derived mesenchymal stem cells transplantation, many mouse anti-human nuclei monoclonal antibody-FITC positive cells were colonized in myeloid tissue. These results showed that human amnion-derived mesenchymal stem cells transplantation can remarkably ameliorate hematopoietic function in cisplatin induced myelosuppression mice.
