Scientists 3D Print a 'Tumor' of Cancer Cells

Using 3D printing, researchers have made a tumor-like lump of cancer cells in the lab, and they say this lump shows a greater resemblance to natural cancer than do the two-dimensional cultured cells grown in a lab dish.

This more realistic representation of a tumor could aid studies on cancer and drug treatments, the researchers said.

To build the tumor-like structure, the researchers mixed gelatin, fibrous proteins and cervical cancer cells, then fed the resulting mixture into a 3D cell printer they had developed. Layer by layer, the printer produced a grid structure, 10 millimeters in width and length, and 2 millimeters in height Read more...
