Intricate sugar networks dissolve to create pathways for blood in lab-grown tissues. Bioengineers have shown they can keep densely packed cells alive in lab-grown tissues by creating complex networks of branching blood vessels from templates of 3D-printed sugar.
Powdered sugar is the special ingredient in a Rice University recipe for mimicking the body’s intricate, branching blood vessels in lab-grown tissues.
In research published in the journal Nature Biomedical Engineering, Rice bioengineers showed they could keep densely packed cells alive for two weeks in relatively large constructs.
“One of the biggest hurdles to e...
