Using a patient’s cells researchers 3D-printed heart, and it gives a hope that using this technique they can heal the hearts; also they can transplant engineered new ones. Tal Dvir, a professor of Biotechnology and Cell Biology, stated that it is for the first time that anybody successfully engineered & printed a reptile of a whole heart using blood vessels. Cells, chambers, and ventricles. Moreover, he is also the senior research author that published on Monday.
The heart printing process needed a biopsy of the fatty tissues that present around the abdominal organs. Researchers working on this mission, detached the tissue cells from the remaining content, specifically the extracellular matrix that links the cells. After that those cells reprogrammed to turn into stem cells having the ability to discriminate into the cells of the heart. Furthermore, the matrix processed into a modified hydrogel that further used as the printing ink.

At first, the hydrogel and the cells used to make heart patches along with blood vessels as well as from there, a whole heart. Dvir said that their 3D-printed heart is small at this stage which is just equal to the size of the rabbit’s heart. However, the same technology needed to 3D-print the human heart. In the past, a scientist only able to print simple tissues deprived of the blood vessels.
Cardiovascular is the Prominent Death Cause in Developing Countries
The primary cause of death in developing countries is the disease of cardiovascular. To treat the condition of last stage heart failure the only technique is to transplant the heart. The authors point out the importance of these developing techniques like 3D-printing of heart.
In addition, Dvir also described that with the help of patient’s cells they could engineering the organs and tissues. He said that it is essential to eliminate the risk of rejection of implant that jeopardizes the success of these type of treatments by the biocompatibility of engineered materials. Further, he gives details that in the next step researchers aim to train the hearts to work like hearts. The cells required to attain a pumping ability, they can at present contract, whereas they wanted them to work together.
It is the future plan of the researchers that if they are successful then they will transplant the 3D printed heart in animals and after successful transplantation, they will do the same thing in humans. Dvir hoped that might be during the upcoming ten years there will be printers in the premium hospitals of the world that will print the organs and these doing will be a part of daily routine.
