    Abstract:
    Recombinant human growth hormone (rhGH) was administered to mice after syngeneic bone marrow transplantation (BMT) to determine its effect on hematopoietic reconstitution. BALB/c mice were given 10 microg intraperitoneal injections of rhGH every other day for a total of 10 injections following syngeneic BMT. Mice that received rhGH exhibited significant increases in total hematopoietic progenitor cell content (colony-forming unit-culture) in both bone marrow and spleen. Erythroid cell progenitor content (burst-forming unit-erythroid) was also significantly increased after rhGH treatment. Analysis of peripheral blood indicated that administration of rhGH resulted in significant increases in the rate of white blood cell and platelet recovery. Granulocyte marker 8C5+ cells were also increased in the bone marrow and spleens of treated mice. Red blood cell, hematocrit, and hemoglobin levels were increased at all time points after rhGH treatment. No significant pathologic effects or weight gain were observed in mice receiving repeated injections of 10 microg rhGH. Thus, rhGH administration after syngeneic BMT promoted multilineage hematopoietic reconstitution and may be of clinical use for accelerating hematopoiesis after autologous BMT.
