Scientists Have Finally Grown a Real Human Heart SUBSCRIBE: https://youtu.be/nE2uhv-ZCSw : A great number of people throughout the world need a heart transplant, but only a few of them will get one. And even if they do, there’s a high risk that their body will reject the new heart. It’s pretty sad, I know. But that all may change any day now since scientists seem to have found a way to grow functioning hearts in the lab!

– Most human organs can regenerate their cells after they experience some damage. Unfortunately, this doesn’t refer to the heart.
– In 2015, a group of researchers from Harvard Medical School and Massachusetts General Hospital announced that they’d figured out how to deal with the issue of organ shortage.
– The answer lies in human skin cells, which can regenerate human heart tissue.
– First of all, the scientists stripped the hearts of part of their cells. After that, they used an innovative technique to turn adult skin cells into special stem cells that were capable of creating different cell types.
– As a result, in two weeks, the scientists got hearts with well-developed structure and tissue. They looked exactly like any other immature human heart.
– The researchers do currently have a plan that will help them achieve their aim. They want to increase the number of versatile stem cells.
– Scientists from the Ohio State University have grown a tiny brain about the size of a pencil eraser. This organoid is genetically similar to the brain of a 5-week-old fetus.
– In 2013, a group of Australian scientists from Murdoch Children’s Research Institute and the University of Queensland cultivated a mini-kidney from stem cells.
– That same year, scientists at New York’s Weill Cornell Medical College managed to 3D-print human ears for the first time!
– A tiny human stomach about 0.1 inches in diameter took just a month to grow in a Petri dish.
– Researchers from several universities collaborated and grew 3D mini-lungs. These organoids had both well-developed airway structures and lung sacks.
– An international team of scientists managed to grow a working food pipe at Kuban State Medical University in Russia. It took them a mere 3 weeks, and they used stem cells to pull it off.
