| Research Abstract |
Previously, we evaluated the therapeutic efficacy of the prodrugs and chemosensitivity gene therapies for malignant gliomas. Recently we have evaluated human neural stem/progenitor cells (hNS/PCs) derived from embryonic stem cell as cell sources and some new genes for molecular therapies for malignant gliomas and other neurogenic disorders.
Firstly, we investigated the ability of neural stem/progenitor cells on dementia in the mouse model of nucleus basalis of Meynert lesion. This new therapy may be feasible for the treatment of Alzheimer's disease (J Med Invest 53 : 61-69, 2006).
Secondly, we examined the YKL-40 gene in human glioblastomas. Based on data from the microarray expression, the YKL-40 gene has been identified as one of the most over-expressed genes in human glioblastomas and the YKL-40 inhibited U87 cell growth, and a significant increase of U87 cells in the GI phase was observed. The gene therapy using the YKL-40 may be feasible for the treatment of malignant gliomas.
Recently, we have successfully evaluated human neural stem/progenitor cells (hNS/PCs) as cell sources for cell replacement therapies for neurological disorders, by examining the alteration of in vitro and in vivo property of long-term expanded hNS/PCs, and by evaluating tumorigenic potentials of hNS/PCs in vivo for up to 6 months by bioluminescent imaging and histological analysis.
