ABSTRACT
<p><b>OBJECTIVE</b>To investigate the expression of mdr1 gene in hematopoietic cells of a murine bone marrow transplantation model and to explore the feasibility of transferring mdr1 gene into hematopoietic cells to pro-vent myelosuppression from chemotherapy.</p><p><b>METHODS</b>mdr1 gene was transferred into hematopoietic cells of murine bone marrow by retrovirus vector. The expression and function of mdr1 gene in vivo was tested in a murine bone marrow transplantation model.</p><p><b>RESULTS</b>(1) mdr1 gene was successfully transferred into murine MNC, the transduction rate was 35%. (2) mdr1 gene transferred murine bone marrow transplantation model was established successfully by scheduled-bone marrow transplantation method. (3) In 1 approximately 5 months period, stable and effective expression of mdr1 gene could be detected in hematopoietic cells of the recipient mouse, the percentage of mdr1 gene expression cells in recipient's hematopoietic cells decreased monthly to 8.0%, 8.0%, 7.5%, 4.0% and 3.0%. (4) mdr1 expression hematopoietic cells had efficient resistance to chemotherapy.</p><p><b>CONCLUSION</b>It is an effective approach to transfer mdr1 gene into hematopoietic cells for preventing myelosuppression in chemotherapy.</p>
