The heart transplant is often the only option for patients suffering from serious heart disease. However, the number of heart donors is limited, whereas patients need heart transplants are too large, this leads to shortage of heart for transplant. Fortunately scientists have successfully Isreal 3D printing technology application in medicine in the printing of the heart, opening up new vistas for patients who need heart transplants.
This study by scientists at Tel Aviv University, published in the Journal of Advanced Science on April 15 last. In this article, let’s Hello Bacsi find out, scientists Isreal did it how nhé!
Whether humans can create a heart or not?
Recently, researchers at Tel Aviv University in Israel has revealed a study can answer that question. In his latest message, they claim to have successfully used a 3D printer to create biological heart tissue complete with blood vessels and heart of people.
The researchers call this “medical breakthrough” because it can help improve the likelihood of success of heart transplantation. However, the heart of this 3D printing is still a certain number of limitations. These limitations include:
First, the heart is only the size of a rabbit heart. In the event press conference at Tel Aviv University, scientists have announced a 3D printed heart shaped with a cherry, are soaked in a liquid. Scientists say they can use the same technique to create a heart-sized real human heart.
Second, although the cells in 3D heart may shrink, but we still do not have the ability to pump blood. Researchers need to figure out how to help this heart can act as a real human heart.
Dr. Tal Dvir, head of projects at the Faculty of Biology and Molecular Biology of the cell belonging to the Tel Aviv University, said: “This heart is made up of human cells and other biological materials of patients workers. In our process, these materials act as the bioink (biological ink). These are materials which are composed of sugar and proteins, can be used to print complex 3D models. This is not the first heart in 3D, but the heart is not complete before because no vascular cells and clear “.
He added that the researchers expected to conduct heart transplant 3D on animal body next year. He said: “Maybe in 10 years, the best hospitals in the world will be equipped with printers organs and organ transplants can be carried out more often.” However, he hoped that these hospitals may begin in other parts of the heart easier next time.
The application of 3D printing technology in medicine can help solve the problems of rejection
A heart in 3D can fix the most serious related to implants, it is the patient’s body excreted body new offices.
In the application of 3D printing technology in medicine, the researchers from Tel Aviv University suggest using biopsy of adipose tissue of the patient (in the process of developing a hydrogel personalized) as a kind of ink needed to print heart.
Dr. Dvir said: “Changing the biocompatibility of materials engineering is very important to eliminate the risk of rejection when transplanted organs, it directly affected the outcome of the treatments “.
That way, in 3D heart and other organs of humans, basically can be customized to fit each specific patient.
He also hoped that the application of 3D printing techniques in medicine will help the organ become simpler.
However, there are still many challenges when applying this technique to the treatment. The resolution of the current 3D printer is still limited, we hardly can print all the small blood vessels. Researchers need to determine how to divide the cells to ensure the amount of tissue needed for a real human heart.
Nevertheless, this is still a significant step towards modern medicine by the application of 3D printing technology to create a large heart as true heart is very feasible.
