Bioengineers clear major hurdle on path to 3D printing replacement organs

from Rice University via Medical Xpress

Bioengineers have cleared a major hurdle on the path to 3-D printing replacement organs with a breakthrough technique for bioprinting tissues. The new innovation allows scientists to create exquisitely entangled vascular networks that mimic the body's natural passageways for blood, air, lymph and other vital fluids. The research is featured on the cover of the week of April 29's issue of Science. It includes a visually stunning proof-of-principle—a hydrogel model of a lung-mimicking air sac in which airways deliver oxygen to surrounding blood vessels. more
