Chinese 3D printer research expert July 5th, for decades, researchers have undoubtedly been able to live and work in the 2D paradigm, and have achieved considerable progress in relying on basic equipment such as petri dishes for testing and experimentation. progress. However, the ability to 3D print (or bioprint) tissues has multiplied the resources of scientists. Many 3D printers now test drugs on 3D printed heart tissue for in-depth research.
Although there are many advantages in bioprinting, it would definitely be better to cancel laboratory experiments on animals. Chinese 3D printer research experts said: “In a Petri dish, all cells are arranged in 2D, this is just a kind of cell.” Professor TAU Dvir, the scientist responsible for developing the world’s first working 3D printed heart. She added: “In contrast, our engineering organization is 3D printed, so it is more like real heart tissue.”
“Our printed tissue contains myocardium, blood vessels, and extracellular matrix. These cells connect different cells through biochemical, mechanical, and electrical means. The transfer from a petri dish to a 3D printed tissue can significantly improve drug testing, saving valuable time and Money, hoping to produce safer and more effective drugs. Our ultimate goal is to design the entire human heart, including all different chambers, valves, arteries and veins-the best analogs of this complex organ-to get more Good toxicology screening process.” In fact, this new study is an extension of previous work to regenerate the heart of patients with cardiovascular disease using 3D printed heart patches. Patches are the main example of specific treatments for patients, because patches are made by removing fat tissue from the patients themselves.
During the research project, Chinese 3D printer research experts were also able to 3D print “integrated structures”, including the entire heart. Other scientists around the world have also conducted research on the development of bioprinted heart tissue, new bio-inks, and stent-free heart structures. As the researchers expect, in the next decade or so, 3D printing will be specific to the patient’s human organs, because patients no longer need to worry about waiting lists (death during this long period of time) or transplant rejection. , Medicine will change.
