Microscopy images of Alg and Alg/Alg-S (a) P-hTMES and (b) I-hTMES. Imaging shown in upper panels in (a)-(b) was conducted using epifluorescence microscopy (Zeiss Axio Observer.Z1), 5X magnification, using 2 μm Z-stacking, with MCF7 labeled with CFSE (green), and fibroblasts with CMAC (blue), Scale bar: 200 μm; Imaging of scaffolds in two lower panels in (a)-(b) was performed by confocal microscopy (Zeiss LSM 880) with 20X magnification, using 2 μm Z-stacking, with MCF7 labeled with CFSE (green), macrophages with CMPTX (red) and cell nuclei with Hoechst 33342 (blue), Scale bar: 20 μm.
