Objective: To investigate the long-term expression of MDR1 gene in hematopoietic cells with a murine bone marrow transplantation model and to explore if it is a stable and effective approach that MDR1 gene was transferred into hematopoietic cells to provent myelosuppression in chemotherapy.

Methods: MDR1 gene was transferred into hematopoietic cells of murine bone marrow with plasmid pHaMDR1/A by the mediation of retrovirus vecter.  The expression and function of MDR1 gene in different phase was tested in vivo by bone marrow transplantation murine model.

Results: MDR1 gene was transferred into hematopoietic cells of murine bone marrow successfully, within 5 months, stable and effective expression could be tested in hematopoietic cells of murine bone marrow in vivo. the ratio of MDR1 gene transferred cells in recipient's hematopoietic cells decreased in every month: 8%, 8%, 7.5%, 4%, 3% .

Conclusion: it is a stable and long-term approach that MDR1 gene is transferred into hematopoietic cells to prevent myelosuppression in chemotherapy.
