@lowpolyshorts: In 2017, the Worcester Polytechnic Institute tackled a major issue: 3D printers simply couldn't replicate the tiny capillary networks needed to keep large tissue samples alive. The WPI team realized that the vein structures in spinach leaves evolved to transport water and nutrients in a pattern nearly identical to human blood vessels, so they used a detergent to strip away the plant matter and leave behind a clear cellulose scaffold. When they seeded this framework with human cardiomyocytes, the cells successfully latched onto the plant veins and began to beat for up to 21 days, which proved that decellularized plants could serve as a low-cost and effective patch to regenerate damaged heart muscle in patients who have suffered heart attacks.
