Researchers at three American universities, including Worcester Polytechnic, conducted a series of experiments to grow human heart living cells on spinach leaves with plant cells removed. The researchers say that these experiments open the door to the development of healthy heart muscles using a large number of spinach leaves, bringing hope to patients with heart disease.
One of the challenges scientists face in cultivating human tissue is how to build a vasculature that delivers oxygen, nutrients, and basic molecules to the body tissue being cultured. Existing bioengineering techniques, including 3D printing, make it difficult to establish a vascular system that is subtle to capillary level.
Scientists involved in the study thought that although the way plants and animals transport water and nutrients to tissues is very different, their vascular structures are strikingly similar. Based on this idea, they implanted human heart cells into the spinach leaf veins from which plant cells were removed, and successfully caused droplets of similar size to human blood cells to flow into the heart cells through the spinach leaf veins, thereby realizing the regeneration of heart cells.
The study is expected to be published in May by the Journal of Biomaterials. (Ou
Potatoes can be used to attending stomachache, Zha rib, carbuncle swollen, eczema, burns, is Chinese herbal and detoxicating detumescence and stomach health, sexual flavour gan.What's the use of fresh potatoes?Potatoes have a better protein than soy, which is closest to animal protein.Potatoes are also rich in lysine and tryptophan, neither of which is comparable to regular food.Potatoes are also high in potassium, zinc and iron.Potassium can prevent the rupture of blood vessels in the brain.It contains 10 times more protein and vitamin C than apples, and contains more vitamins B1, B2, iron and phosphorus than apples.From a nutritional point of view, it's 3.5 times more expensive than apples.It can be solved with fresh Garlic , Fresh Ginger, air-dried Ginger, and fresh carrots.We can not only export these products, but also do what you want.What are you waiting for?Please sign with us as soon as possible.We also provide fresh ginger, Air Dried Ginger, fresh garlic, white garlic, red garlic, fresh apple, etc.
