Sarcoma Cells (IMAGE) Rice University Caption Sarcoma (bone cancer) cells proliferate on the surface of a 3-D printed scaffold created at Rice University. Experiments at Rice showed that the size of pores in the scaffold, which mimics the extracellular matrix in bone, and the pores' orientation make a difference in how cells proliferate in the presence of a flowing fluid, like blood.
