| Research Abstract |
Recent progress in gene therapy techniques has led to an application of gene therapy to inherited metabolic diseases. In most protocols of gene therapy to inborn errors of metabolism, bone marrow cells and purified bone marrow stem cells are used as the targets. Therapy to patients with inborn errors of metabolism should be started as soon as possible after diagnosis. Therefore, peripheral blood stem cells, more safely and repeatably obtainable from infants than bone marrow stem cells, are a good candidate for the target cells for gene therapy in patients with inherited metabolic diseases. In this projectat, first we developed the effective protocol of purificetion of CD34^+ cells from peripheral and cord blood. Then, we evaluated retro-viral mediated transduction and long-term expression of NeoR gene in CD34_+ cells purified from G-CSF-mobilized peripheral blood of small children and cord blood, and showed that CD34^+ cells in CB or mobilized PB are suitable and realistic targets for retroviral gene transfer protocols for inborn errors of metabolism. Furthermore, we constructed the retro-viral vector containing CAG promoterand glucocerebrosidase cDNA for the effective gene therapy for Gaucher disease.
