NIBIB-funded engineers are designing aortic heart valve replacements made of polymers rather than animal heart tissues. The goal is to optimize valve performance and enable increased use of a minimally-invasive method for valve replacement over open heart surgery.

When cardiovascular disease causes blocked blood vessels, tissues die because the oxygen carried by blood cells cannot reach the tissue. Surgery can remove blockages in large vessels in the heart or legs but is not possible in small vessels. To address this problem, researchers funded by the National Institute of Biomedical Imaging and Bioengineering (NIBIB) designed 3D-printed patches seeded with vessel-inducing endothelial cells in various geometric patterns. Using a mouse model of hindlimb ischemia, the researchers identified specific patch patterns that induced growth of organized, tissue-saving blood vessels, demonstrating the potential for the novel technology to address this significant public health problem.

Fluorescent quantum dots are valuable tools used to tag and image biological processes in live animals. However, precise fluorescent imaging at the cellular and molecular levels has not been possible because of non-specific fluorescence and light scattering by surrounding tissues. Now researchers have resolved many of these problems by using SWIR quantum dots in live mice to image working organs, take metabolic measurements, and track microvascular blood flow in normal brain and brain tumors.
