If it looks like a spinach leaf and tastes like a spinach leaf, then how can it be used to help grow heart tissue? Well, that’s exactly what researchers at the Worcester Polytechnic Institute (WPI) at the University of Wisconsin-Madison intend to do.
Joshua Gershlak, the first author on “Crossing kingdoms: Using decellularized plants as perfusable tissue engineering scaffolds”, explained:
“I had done decellularization work on human hearts before, and when I looked at the spinach leaf its stem reminded me of an aorta. So I thought, let’s perfuse right through the stem. We weren’t sure it would work, but it turned out to be pretty easy and replicable. It’s working in many other plants.”
Cultivating Tissue Growth With Plants Is Nothing New
This isn’t the first time researchers at the University of Wisconsin-Madison have tested plant-based scaffolds in place of costlier synthetic alternatives.
“Plants are extraordinarily good at cultivating new tissues and organs, and there are thousands of different plant species readily available.” As noted by Dr. Murphy in a related study, “They represent a tremendous feedstock of new materials for tissue engineering applications.” In Murphy’s study, the plant-based scaffolds used were made from parsley, orchid, wasabi, and bamboo.
In the latest study, however, the focus fell specifically to the spinach leaf. It was the similarity between the leaf’s innate vascular structure that made the researchers curious to see how it would perform as a substitute for the human vessels.
Spinach Leaf as Vascular Structure Substitute
In their paper, the WPI team stated, “Cellulose is biocompatible [and] has been used in a wide variety of regenerative medicine applications, such as cartilage tissue engineering, bone tissue engineering, and wound healing.”
Under normal circumstances, the thin veins of the spinach leaf deliver water and nutrients to the rest of its cells. It’s the hope of the WPI researchers to be able to use those veins—after being treated with an overlay of human cells—to transport blood through human tissue.
