Here is Our future, April 15/2019 - Researchers at Tel Aviv University have developed a world's first 3-D print Heart using a patient's cells and biological materials.

Scientists have already built synthetic hearts and bio-engineered tissues using a human patient's cells. But, the latest achievement is that the 1st time scientists have created a complex organ that also called heart with biological materials.

A material scientist and professor of molecular cell biology at Tel Aviv University (TAU) - lead researcher Tal Dvir, said in the news that - This is the first time when anybody anyplace has successfully engineered and printed a whole heart replete with cells, blood vessels, ventricles, and chambers of the heart.

The concept of this achievement could help the way for a new type of organ transplant. For patients that suffer from heart failure, a just a single solution is the heart transplant. But...but there is heavy lack of heart donors.

Dvir said that-This world-first 3-D printed heart is created using human cells and specific biological materials. In our process these biological materials serve as the bio-inks, substances made of sugars and proteins that are used for 3D printing of complex tissue models, he also said that his results demonstrate the capability of our methodology for designing personalized tissue and organ substitution in the future.

The 3D heart is the size of a rabbit heart.

The heart scientists say that the printed heart couldn't be used in a human transplant activity. Actually, the 3D heart is the size of a rabbit's heart, and it doesn't work now. However, Dvir said that to print a human-size (12 cm long and 9-8 cm wide) heart require basically the same technology.

Researchers detailed their invention in the journal Advanced Science you can also check them.

To create the bio-inks that is used to build the heart, the researcher took fatty cells from one human patient and reinvented them to progress toward becoming pluripotent stem cells before separating them into cardiac and endothelial cells, which stature the vascular interior. Scientists mixed the separated cells to form bio-inks, which were used to layered onto scaffolding using a specialized 3D printer to form a small size-heart.

Dvir said - The biocompatibility of engineered materials is essential to take out the risk of implant rejection, which put at risk the success of such treatments, He also told figuratively that - the biomaterial should possess the same biochemical, mechanical and topographical properties of the patient's own tissues. Here, we can report a simple way to deal with 3D-print thick, vascularized and perfusable cardiac tissues that mostly coordinate with immunological, cellular, biochemical and anatomical properties of a patient.

Actually, the 3D-printed heart cells only now contract but they're not synchronized or entirely functional. Scientists need to better and most better program the 3D-printed heart and its several components and cells to coordinate their movements, so the heart doesn't just look like a natural heart, but in addition, but also work as the natural heart.

When researchers print a complete heart with functions as it should, then they transplant 3-D-printed hearts into animals, to test their functionality that how the heart works.
