In Chicago printed mini human-heart

Print bodies — is undoubtedly the future of medicine and transplantologii
Modern bio-printers are already able quite successfully to produce printing fabrics that is even possible . But the printing of complete organs with a complex internal structure — it's still quite difficult to master the technology. However, medicine does not stand still and the new development of scientists from Chicago suggests that it is possible we will soon forget about the lack of donor organs. After all, the American experts were able to print fully functional human heart. However, while in the thumbnail.
Who printed the human heart?
According to the publication Еngadget for development is a Chicago biotech company BIOLIFE4D. The company was founded in 2016 to come from a variety of areas from electronics to medicine and reprogramming of stem cells. All the experts came together with a single purpose — to reform the system of obtaining donor organs by creating their artificial counterparts. The first project scientists was the creation of an artificial heart using the bio-printer. About these developments we regularly write in our
And just yesterday the representatives of BIOLIFE4D said . However, in order to experiment (as this is the first experience company's) heart, it was decided to print in miniature. The tiny heart has the same structure and functionality as the full-sized heart. The body was printed with the help taken from volunteers of cardiomyocytes (cardiac muscle cells). These cells were reprogrammed so that they could «multiply». This approach is useful for a number of reasons. First, this way you can create the most exact copy of cell structures and whole organs, and secondly if you take these cells from a hypothetical patient who needed a heart transplant, and grow a new organ after transplant the body won't reject the new heart, as at a cellular level, this body is no different from «native».
Here is the printed human heart in miniature
It is also Worth noting the fact that BIOLIFE4D earlier this year was able to print the individual components of the heart including the valves, ventricles and blood vessels. And they did not need to produce a fence of the cells of the heart. It was enough white blood cells of the patient are reprogrammed into induced pluripotent stem cells (iPS cells) that can differentiate into various cell types, including those needed for the experiment.
At the moment, the company is aiming to print on the bio-printer full-size, functioning human heart. Of course, BIOLIFE4D — not the only company that creates bodies for 3D printing. For example, researchers from tel Aviv University also printed a heart on a 3D printer earlier this year. But experts from the Massachusetts Institute of technology (MIT) have managed to make the printing of complex vascular networks that are necessary to maintain the work and functioning of artificial organs. So that work in this area is an ongoing process and I hope that very soon scientists will find a way to create fully functional organs for transplantation and will thus save many lives.
