Bright-field images of hMSC cultured in control (FBS-Medium) (a) and XF-Medium (b) in passage 5 after 6 days in culture. Elongated cells with sharp ramifications are highlighted in orange (continuous line), and cells with a more polygonal and rounded shape are highlighted in blue (discontinuous line). (c) Frequency distribution of hMSC circularity of cells expanded in FBS- or XF-Medium (3 samples, 2 fields per sample, 13–20 cells per field counted; ).
(a) FBS-Medium
