Research Abstract

After confirmation of the therapeutic effects of encapsulated ES cell- or NT2 cell-derived dopaminergic neurons on Parkinson's diming= model of rats, adult rat-derived neural stem/progenitor cells were focused on. Encapsulated adult rat-derived neural stem/progenitor calls survived for 2 months with or without prospective neuronal differentiation without tumor formation. Then, neural stem/progenitor cells were isolated from adult macaque subventricular zone or hippocampus. The growth speed of the cells was so slow that it took at least one and a half months to he amplified for encapsulation. Type I collagen remarkably ameliorated the survival of encapsulated neural stem/progenitor rolls and the surviving rate of the encapsulated macaque cells were almost the same as that of rat cells. Neuronal differentiation of encapsulated undifferentiated macaque-derived neural stern/progenitor cells was little with much glial differentiation. Encapsulated undifferentiated cells survived for 1 month in a Parkinson's disease model of macaque, although it did not significantly ameliorate abnormal behavior On the other hand, macaque-derived neural stern/progenitor rolls could be encapsulated after neuronal differentiation. Dopaminergic differentiation with subsequent encapsulation resulted in dopamine-secretion from the capsule. Encapsulated differentiated rolls improved the behavioral scores, indicating that encapsulated dopaminergic neurons derived from adult macaque neural stem/progenitor cells had therapeutic effects on a Parkinson's disease model of macaque with no tumor formation by thstiff capsule wall Clinical application might be achievable in the figure, although several preclinical studies remain to be solved.
