Tissue engineers are beginning to tackle the task of building the complex scaffolding necessary for 3D production of complicated human organs such as the heart. Researchers at the Massachusetts Institute of Technology are currently using techniques from the microelectronics industry to stack porous biorubber sheets. The aim is to replicate the ability of heart tissue to behave differently, depending on the way it is stretched. At the Mayo Clinic’s Center for Regenerative Medicine, a bio-printer has been installed that can print the scaffold and cells needed for a heart valve.
