    Abstract:
    AIM: To study effects of parathyroid hormone (PTH) used in therapy of osteoporosis on hemopoiesis in long-term culture of human bone marrow (LCBM) in terms of its potential influence on stem hemopoietic and stromal cells. MATERIAL AND METHODS: For a long time LCBM was treated with PTH (1-34) and compared for cell production, concentration of late and early hemopoietic precursors. Maintenance of hemopoiesis and adhesion at early hemopoiesis precursors on the stromal sublayers treated with PTH (1-34) was used as a functional test. A relative level of expression of genes participating in regulating proliferation and self-support of stem hemopoietic cells was studied. RESULTS: PTH (1-34) in the above concentrations did not affect hemopoiesis in LCBM. Stromal sublayer treated with PTH (1-34) for a long time supports cell precursors better, their adhesion to such sublayers enhances. CONCLUSION: PTH (1-34) in pharmacological but small concentrations had no irreversible effects on hemopoiesis, i.e. contraindications for its use in the treatment of osteoporosis were not revealed.
