Sugar used to 3D print complex vascular networks

Researchers from Rice University (TX, USA) have used powdered sugar to 3D print blood vessel templates, keeping densely packed cells alive for 2 weeks. A team of researchers from Rice University (TX, USA) has used powdered sugar to 3D print templates for blood vessel production, keeping densely packed living cells in large constructs alive for 2 weeks. "One of the biggest hurdles to engineering clinically relevant tissues is packing a large tissue structure with hundreds of millions of living cells. Delivering enough oxygen and nutrients to all the cells across that large volume of tissue becomes a monumental challenge,” explained...
