Human 3D heart

Human heart made from human cells created with 3D printer for first time

For the very first time in the history of mankind, scientists have been successful in making a working, vascularized build heart. This is made using human cells by printing it in 3D. Advanced Science published this ground-breaking advancement that could change the fate of medicine forever. Professor Tal Dvir of Tel Aviv University proudly said that this the first time that anybody in this world has effectively not only engineered but printed an entire heart which is loaded with cells, blood vessels, ventricles, and chambers.

He furthered explained that human cells and patient-specified biological materials were used in the making. These materials made of sugars and proteins served a very useful purpose in 3D printing of the complex heart model. The outcomes clearly show the capability of the methodology and research for building customized tissue and organ replacement for the time to come.

Further details regarding the engineering of the 3D heart have also been reported. The fatty tissue was taken from a healthy patient and separated into cellular and a-cellular substances. These cells were reprogrammed to form pluripotent stem cells and served the purpose of printing the ink used. Once this was done these were mixed with the hydrogel and patient-specific cardiac patches and blood vessels were created. In the whole process, it is very important to take care that the biomaterial should be same in all aspects with the patient’s own tissues as told by Dvir.

The heart was developed using human cells and patient-specified bio-materials, yet the heart is too small to be used for organ transplants as it compares to the size of a rabbit’s heart. There is potential to develop an enlarged heart as assured by Dvir as the development requires the use of very same technology.

The study took its inspiration from the prevalence of cardiac diseases in the states of Israel and the US as problems account to a large number of deaths for both men and women. With further scientific progress, Dvir hoped that they will soon able to teach the heart to not just look like a heart but also behave like one. There is a strong possibility in the coming ten years that hospitals will be equipped with organ printers if this research is proved effective.
