Figure 1: Cultures of undifferentiated rMSCs at different passages. At P1 rMSC cultures were morphologically heterogeneous (a). At P2 rMSC cultures consisted of a more homogeneous population of cells, most of which had a large flattened morphology (arrow). Relatively elongated cells were also present (arrow head) (b). At P50 rMSCs lost their morphology appearing more rounded (c). Bars:100 μm.
