Outline of Final Research Achievements |
In this study, we investigate the pathophysiological mechanism of bone lesion in Mucopolysaccharidosis type II (MPS II) , and study the effect of ex vivo gene therapy targeting for hematopoietic stem cells. At first, we investigated the pathology of bone disorder in MPS II mouse model to detect items as control for evaluating therapeutic effects, and searched for bio-markers reflecting the progress of bone lesion. As a result, in the pathological study the balance between bone formation and resorption has been inclined to bone formation in this model, but we could not detect the efficient bio-marker of mRNA reflecting bone formation and resorption for evaluating the therapeutic effect. We are currently evaluating the effect of ex vivo gene therapy for MPS II mouse model using recombinant lentivirus vector.
