Abstract
Canavan disease (CD) is an autosomal recessive disorder that leads to spongy degeneration in the white matter of the brain. Aspartoacylase (ASPA) synthesizing cells, oligodendrocytes, are lost in CD. Transplantation of neural progenitor cells (NPCs) offers an interesting therapeutic approach for treating neurodegenerative diseases by replacing the lost cells. Therefore, the NPCs transplantation to the brain of the CD mouse was studied. Injection of mouse NPCs to the striatum and cerebellum of juvenile CD mouse showed numerous BrdU positive cells at 1 month after injection. The same result was also observed in the adult CD mouse brain after 5 weeks of post-transplantation period. The implanted cells differentiated into oligodendrocytes and fibrous astrocytes, as observed using glial cell marker. This is the first report to describe the survival, distribution and differentiation of NPCs within the brain of CD mouse and a first step toward the potential clinical use of cell therapy to treat CD.
