Human body transplantation with plant system… is weird to hear but it is something going to happen in future.

Spinach one the best source of vitamines, minerals, protiens, not only spinach but there are hundred of plant which are beneficial to human from our food to the cosmetics we use in our daily life, but think if plants can used for organ trnsplantation it will be a new revolution in our medical history. Doctors have been reasearching for several years to use spinach leaves for heart transplantation.

It is been a failure to produce artificial heart for organ transplantation because we’re not that good at growing blood vessels, and tissues need blood vessels to, well, stay alive. The blood vessels in our own body range from the aorta’s whopping 3 centimeter diameter to capillaries as thin as 5 microns—15 times thinner than a human hair. Our current techniques aren’t refined enough to create fluid channels that tiny, so bioengineers are hard at work finding other ways to make it happen. So if a person having non fuction heart muscels its very difficult to replace the heart with artificial heart.

One thing we can do is start with an actual organ, like a heart, and stripping it of its existing cells so that all you have left is its underlying structure. It already has blood vessels, after all. From there, the hope is that you could use stem cells to create human heart tissue that matches that of a transplant recipient. There’s just one problem: you need a heart first. It would be great if you could do the same thing with something easier to come by—spinach leaves, for example. “I had done decellularization work on human hearts before,” the study’s lead author Joshua Gershlak said in a press release, “and when I looked at the spinach leaf its stem reminded me of an aorta.” said by Joshua Gershlak.

He figured out a way to remove the plant cells by sending a detergent solution straight through the spinach leaf’s stem into its veins. After that, he had a framework made of harmless cellulose. The team bathed that framework in live human cells, these live human cells soon began growing inside of the tiny veins and beating on the surface of the now-skeletonized leaf. Once it was colonized by human heart cells, the researchers sent fluids and blood-cell-sized microbeads through the veins, demonstrating that blood could flow through the system.

Even though their beating spinach leaf looks like a miniature heart, the researchers don’t plan on replacing entire human hearts with stuff from the salad bar. Instead, they hope to use the technique to grow layers of human heart muscle, which could replace the portions damaged by heart attacks. The technique doesn’t just work with spinach—in fact, this very study also tried it with parsley, Artemesia annua (sweet wormwood), and peanut hairy roots. Different plants could be handy for different purposes. The spinach leaf might be better suited for a highly vascularized tissue, like cardiac tissue, whereas the cylindrical hollow structure of the stem of Impatiens capensis (jewelweed) might better suit an arterial graft. Conversely, the vascular columns of wood might be useful in bone engineering due to their relative strength and geometries. We all knew greens were good for us, but we didn’t realize they were this good.
