Microfluidic 3D co-culture of human BMSCs and PC3 prostate cancer cells. (a) Schematic of PC3 human prostate cancer cell seeding into a scaffold-chip and subsequent perfusion culture. (b) Fluorescent image of Luc-GFP PC3 prostate cancer cells captured in a microfluidic scaffold after 3 days perfusion culture. PC3 cells are red colored to distinguish from human BMSCs. (c) Schematic of human BMSCs seeding into a scaffold-chip by single rapid injection and subsequent perfusion culture. (d) 3D confocal images of post 3 days perfusion culture show that BMSCs stably adhered on pore surface and well distributed both axial and lateral directions of an integrated hydrogel scaffold. (e,f) Fluorescent images of co-culture microfluidic chip show engrafted human prostate tumor cells in 3D microenvironment.
