A 3-D sugar network to feed bioengineered organs: moldable, biodegradable, and useable. In a word – Sweet!!
3D Printed Sugar Network to feed Engineered Organs
Reporter: Irina Robu, PhD
“Tissue engineers have long dreamed of building an organ in a dish. But without vessels running through the tissue, cells in the centre starve and suffocate.
Now, US researchers can build vessels into a cell-containing gel – the beginnings of a thick tissue. Scientists form the gel around a lattice of printed sugar fibres. The fibres dissolve after the gel sets, leaving a network of channels that carry nutrients like blood vessels.
For the past decade, tissue engineers have looked for ways to build a 3D tissue in such a way that vessels are immediately available to feed growing cells. One way to create these vessels uses a tiny silicon template to pattern grooves in a sheet of cell-containing gel. Covering these cut outs with another sheet of engineered tissue creates enclosed channels. While these sheets can be…
