Scientists print self-assembling 'living tissue'

Three-dimensional printer uses water and oil to create lipid networks that mimic biological feats.

Researchers have created networks of water droplets that mimic some properties of cells in biological tissues. Using a three-dimensional printer, a team at the University of Oxford, UK, assembled tiny water droplets into a jelly-like material that can flex like a muscle and transmit electric signals like chains of neurons. The work is published today in Science¹.
