[Effect of antithymocyte globulin on bone marrow colony-forming capacity during defective myelopoiesis].

The effect of antithymocytic globulin (ATG) on colony-forming and claster-forming capacity (CFC and ClFC) of the bone marrow in vitro was studied in patients with hypoplastic anemia. 15 children in the initial stage of the disease and 6 patients before and after splenectomy were examined.
