Researchers at the U.K’s University of Bristol’s School of Cellular and Molecular Medicine announced a new advancement in bio-printing. They developed a bio-ink that is comprised of stem cells and two polymers – one naturally occurring and the other artificial. The polymers provide structural support to the stem cells that can then be directed to differentiate into the appropriate tissue. The addition of the phase-change polymer component to the bio-ink allows the printed organ to quickly develop the structural integrity necessary to introduce cell nutrients to the stem cells.
