Confocal images of the PIECs on TCPs, SF fabrics and self-assembled (ALG/RSF)n SF fabrics with the cell nuclei stained with DAPI (Blue) and F-actin stained with phalloidin-TRITC (Red).
(a) TCPs cultured for 1 day, (b) SF fabric cultured for 1 day, (c) self-assembled (ALG/RSF)1.5 SF fabric cultured for 1 day, (d) self-assembled (ALG/RSF)9.5 SF fabric cultured for 1 day, (e) TCPs cultured for 3 days, (f) SF fabric cultured for 3 days, (g) self-assembled (ALG/RSF)1.5 SF fabric cultured for 3 days, and (h) self-assembled (ALG/RSF)9.5 SF fabric cultured for 3 days. The scale bar is 50 μm.
