Aim: To investigate the potential of human growth hormone (hGH) to improve human hematopoietic reconstitution in humanized mice. Materials & methods: Immunodeficient mice were conditioned by total body irradiation and transplanted with human CD34+ fetal liver cells. Peripheral blood, spleen and bone marrow were harvested, and levels of human lymphohematopoietic cells were determined by flow cytometry. Results: Supplementation with hGH elevated human lymphohematopoietic chimerism by more than twofold. Treatment with hGH resulted in significantly increased reconstitution of human B cells and myeloid cells in lymphoid organs, enhanced human erythropoiesis in the bone morrow, and improved engraftment of human hematopoietic stem cells. Conclusion: hGH supplementation promotes human lymphohematopoietic reconstitution in humanized mice.
