MSC characterization. A) Representative light microscopy images showing MSC morphologic differences between MDS patient (right) and control (left) with ×10 and ×40 magnification. B) Flow cytometry analysis of MDS-MSC (n = 5) and control-MSC (n = 5) immunophenotype. Histograms show percentage of positive cells for CD90, CD73, CD105, CD14, CD34 and CD45 (p was not significant). C) Differentiation assay. Representative images of MDS (right column) and control (left column) differentiation assays showing adipogenesis stained with Oil Red, osteogenesis stained with Alizarin Red and chondrogenesis stained with Toloudine Blue.
