Co-culture of vascular cells in GelMA. Constructs containing both DsRed-ECFCs and CMFDA-labeled MSCs were cultured for 2, 4 and 6 d using GelMA hydrogels with different methacrylation degrees. (a,b) Numbers of DsRed-ECFCs (a) and CMFDA-MSCs (b) were separately counted at each time point under a fluorescence microscope. (c–h) Representative confocal microscopy images of DsRed-ECFCs (c–e) and CMFDA-MSCs (f–h) after day 6 in co-culture for each methacrylation degree. [28].
