| Research Abstract |
We performed cell transplantation therapy to treat the brain involvement of lysosomal storage diseases. The grafted cells were gradually depleted because of immunological rejection by the host animals. To avoid deleterious immune attack and to achieve sufficient long-term efficacy in brain, development of methods to steer the immune response away from cytotoxic responses or to induce tolerance to the products of therapeutic genes is needed. To overcome this immunological rejection, we carried out brain injection and intravenous administration of mesenchymal stem cells simultaneously to a model mouse of β-galactosidase deficiency. However, we could not show a significant deference in the duration of engrafting between the brain injection only and the simultaneous injection of brain and vein.
