摘要：This experiment sought to observe the migration and distribution of bone mesenchymal stem cells transfected with the cytosine deaminase gene (BMSCs-CD/eGFP) after transplantation in vivo through three pathways. In addition, we examined the tropism of these cells to glioma. Intracranial C6 glioma models were established in Sprague-Dawley rats using an intracranial stereotactic inoculation method. When tumors were 7 days old, rats were inoculated with 1x10(6) BMSCs-CD/eGFP cells via the tumor-bearing internal carotid artery, the contralateral hemisphere and the tumor-bearing glioma. Fluorescence microscopy revealed that BMSCs-CD/eGFP exhibited a strong capacity for migration to tumors. BMSCs-CD/eGFP transplanted via the tumor-bearing internal carotid artery were observed to distribute in glioma tissues. BMSCs-CD/eGFP inoculated via the ipsilateral glioma mainly located within and at the edge of glioma tissues. BMSCs-CD/eGFP inoculated via the contralateral hemisphere mainly distributed at the proximal end of the tumor at the incubation site.
