Migration and survival of hAFCs and hCVCs labeled with different SPIOn concentrations.

<p><b>a</b> Cells were labeled with different concentration of SPIOn for 72 hours before migration assay. Data are expressed as a percentage of migrated cells. *p<0.05, **p<0.01 and ***p<0.001 versus respective CTR (control, unlabeled cells). Two way analysis of variance (ANOVA); as specified in the statistical section; <b>b</b> hAFCs and hCVCs labeled with different SPIOn concentrations were used to test SPIOn toxicity by MTS assay. Data are expressed as a percentage of viable cells versus unlabeled cells used as control (CTR). Two way analysis of variance (ANOVA); as specified in the statistical section.
