Abstract
Objective: To clarify the capacity of selective migration of human neural stem cells (hNSCs) to brain tumor stem cells (BTSCs) derived from glioblastoma, we studied the tropism of hNSC to BTSCs in vitro and in vivo. Methods: We cultured BTSCs from GBM tissues by neurosphere culture method, then, investigated the tropism ability of hNSCs to BTSCs using in vitro transwell chamber cell migration assay and in vivo tumor tropism studies. Results: The BTSCs could be obtained from human GBM tissues, and formed neuroshpheres after cultured 7d in vitro, and were CD133- positive and nestin-positive. Theses BTSCs could regenerate a GBM tumor in vivo when implanted intraventricularly. Cell migration assay showed that BTSCs have the capacity to actively attract hNSCs. The fate of hNSCs in vivo can be visualized under confocal fluorescence microscope. hNSCs exhibit extensive tropism toward the site of the tumor and infiltrate tumor foci. Conclusions: BTSCs could be derived rapidly from GBM tissues by neurosphere method. The normal hNSCs possess the capacity to migrate toward BTSCs in vitro and in vivo. The tropism of hNSCs towards brain tumors may provide an additional tool for the treatment of brain cancer.
