Establishment of a Model of Microencapsulated SGC7901 Human Gastric Carcinoma Cells Cocultured with Tumor-Associated Macrophages

Figure 1

Phase contrast imaging of microencapsulated SGC9701 cells. (a) Microencapsulated cells on day 0 as control. (b) After culturing for 7 days, the cells tended to aggregate in spheres. (c) After culturing for 14 days, the spheres expanded rapidly and grew in three dimensions. (d) After culturing for 21 days, the sphere expansion slowed down and spheres showed necrosis in the center. Magnification: 200x.
