<p>(A) Representative flow cytometry histogram with overlay of the two groups showing no difference in CD146 expression after SPION labeling of BMSCs. (B) Bar graph showing mean CD146 expression in FePro labeled and unlabeled BMSC. Note the lack of statistically significant difference in CD146 expression after SPION labeling (solid colored bars), Student t test, p>0.5. Data shown as mean +/− S.D. of CD 146 expression in 5 donors.</p
