title: [In vitro separation of bone marrow nuclear cells with methylcellulose and its application to autologous bone marrow transplantation in patients with leukemia].
abstract: We studied bone marrow separated with 0.05% methylcellulose and cryopreservatized with liquid nitrogen. The separation time was 43 minutes. The collection rates of nuclear cells and CFU-GM were 79.0 +/- 5.10% and 93.0 +/- 3.10% in normal marrow samples and 83.4 +/- 15.45% and 91.0 +/- 8.32% in those of acute leukemia patients. The rate of residual erythocytes was 12.5% and the bone marrow volume could be reduced by 55.2%. Application of this technique to autologous bone marrow transplantation in four patients with acute leukemia reconstituted all of their hemopoietic functions and no toxic side effect was found after transplantation.
