TAMPINES, Singapore—Scientists at the Singapore University of Technology and Design (SUTD) report that they have 3D printed heart cells to control stem cell differentiation in embryoid bodies, which are stem cells packed into small cellular aggregates or spheres. 

PhD student Rupambika Das and Assistant Professor Javier Fernandez 3D printed several micro-scaled physical devices with finely tuned geometries. They then used these devices to demonstrate an unprecedented precision in the directed differentiation of stem cells through the formation of embryoid bodies.
