In this study, we showed that knocking-down interleukin-8 (IL-8) in glioma cells, or its receptor, CXC chemokine receptor 1 (CXCR1) in hUCB-MSCs reduced hUCB-MSC migration toward glioma cells in a Transwell chamber. In contrast, CXCR1-transfected hUCB-MSCs (CXCR1-MSCs) showed a superior capacity to migrate toward glioma cells in a Transwell chamber compared to primary hUCB-MSCs. Furthermore, these transfected cells also demonstrated the same ability to migrate toward tumors in mice bearing intracranial human gliomas as shown by histological and in vivo imaging analysis. Our findings indicate that overexpression of CXCR1 could be a useful tool for MSC-based gene therapy to achieve a sufficient quantity of therapeutic MSCs that are localized within tumors.
