Phenotype identification of MSCs and EPCs.

<p>(A) Flow cytometry analysis for MSCs. The red open histograms indicated the cells which were stained positive for the undifferentiated MSCs markers -CD44 and CD90 and negative for CD 31 and CD34. The black open histograms showed isotype-matched control staining. (B) Flow cytometry analysis for EPCs. The red open histograms indicated the cells which were stained positive for the markers of undifferentiated EPCs - CD133 and CD34, and negative for CD31 and CD11b. The black open histograms showed isotope-matched control staining. (C-E) Fluorescence images of EPCs cultured for 14 days and stained with (C) Dil-Ac-LDL, (D) lectin and (E) DAPI. Bar = 50 µm. (F) Overlay of images of C, D and E.
