3-D printing cancer cells to mimic tumors

A 3-D model of a cancerous tumor using a 3-D printer has been successfully created by researchers. The model consists of a grid structure, 10 mm in width and length, made from gelatin, alginate and fibrin, which recreates the fibrous proteins that make up the extracellular matrix of a tumor. "With further understanding of these 3D models, we can use them to study the development, invasion, metastasis and treatment of cancer using specific cancer cells from patients. We can also use these models to test the efficacy and safety of new cancer treatment therapies and new cancer drugs," the lead author stated.
