New Technique Can Bioprint Living Tissue In Seconds
An anonymous reader quotes Engadget:Bioprinting holds great potential for repairing injuries, testing drugs or replacing whole organs, but it's currently limited in complexity, viability and speed -- you can't just create tissue on a whim. Soon, though, it might be a matter of crafting whatever you need when you need it. Scientists at EPFL and University Medical Center Utrecht have developed an optical system that can bioprint complex, highly viable living tissue in "just a few seconds." It would represent a breakthrough compared to the clunky, layer-based processes of today. The approach, volumetric bioprinting, forms tissue by projecting a laser down a spinning tube containing hydrogel full of stem cells. You can shape the resulting tissue simply by focusing the laser's energy on specific locations to solidify them, creating a useful 3D shape within seconds. After that, it's a matter of introducing endothelial cells to add vessels to the tissue. The resulting tissues are currently just a few inches across. That's still enough to be "clinically useful," EPFL said, and has already been used to print heart-like valves, a complex femur part and a meniscus. It can create interlocking structures, too.Read more of this story at Slashdot.
