Immunophenotypic analysis of the third passage hADSCs by flow cytometry. The fluorescence level detected for the stromal stem cells markers was 95.9% for CD44, 92.04% for CD73, 92.86% for CD90 and 94.6% for CD105, respectively, whereas for the hematopoietic stem cells marker CD34 only 0.3% of the gated cells were fluorescently labeled. The positive zones in the histograms were marked with B in the fluorescence channel 1 (FL1), and with C in the fluorescence channel 2 (FL2), respectively, based on the isotype control antibody.
