However, the unaddressed concerns about the impact of SPIO nanoparticles on stem cell attributes make the feasibility of SPIO labeling uncertain. Here, we show that the labeling of human mesenchymal stem cells (hMSCs) with ferucarbotran can induce epidermal growth factor receptor (EGFR) overexpression. Labeled hMSCs with their overexpressed EGFR were attracted by tumorous EGF and more effectively migrated toward tumor than unlabeled cells, resulting in more potent intrinsic antitumor activity. Moreover, the captured binding of tumorous EGF by overexpressed EGFR of labeled hMSCs blocked EGF/EGFR signaling-derived tumor growth, tumorous angiogenesis, and tumorous VEGF expression also responsible for tumor progression and development. Our results show that the impact of SPIO nanoparticles on stem cell attributes is not necessarily harmful but can be cleverly used to be beneficial to stem cell-based therapy. ? 2011 American Chemical Society. |
