Abstract

The karyotype of AKR mouse lymphoblastic leukemia cell line made resistant to 5-azacytidine was compared with the karyotype of parental line. In relation of 5-azacytidine-resistant line the parental cell have less chromosomes No. 5 and more of No. 17 per karyogram. The increased monosomy has been found in chromosomes No. 5, 6, 7, 8 and 18 in sensitive line and in chromosomes No. 1, 8 and 17 in 5-azacytidine-resistant cells. The highest occurrence of trisomy was present in the chromosomes No. 13 and 16 in both lines. In AKR sensitive cells 89% of karyograms displayed 3 to 13 markers per karyogram while in the resistant line there were only 37% of karyograms with 1 to 11 markers.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
