Fig. 6: In vitro cell behaviour effects of WS2/PCL/CS scaffold.

a Col I secretion; b Viability; and c ALP activity of hMSCs cultured on PCL/CS and WS2/PCL/CS scaffolds. ‘*’ indicates a significant difference (p < 0.05) compared to Ctl. ‘#’ indicates a significant difference (p < 0.05) compared to the PCL/CS scaffold; d F-actin filaments (green) and nuclei (blue) staining of hMSCs cultured on scaffold at different time-points. Scale bar is 200 µm.
