Scientists use 3-D printer to speed human embryonic stem cell research

February 5, 2013

Researchers have been able to engineer tissue samples in the past by combining artificial scaffold-like structures and animal cells. Depositing human embryonic stem cells in cultures using a 3-D printer offers some advantages. In particular, the cells can be positioned in droplets of uniform size cheaper, faster and more easily than using manual methods. This uniformity is important for researchers trying to generate specific cell types. (Scientific American)
