Researchers from the University of Tel Aviv (Israel) have for the first time been able to create blood vessels, ventricles and cameras for a rabbit's organ using a 3D printer, using the patient's cells and biological materials.

 

"In our process, these materials are bio-samples, sugars and protein substances, and they can be used for 3D printing of complex tissues. People in the past have been able to print 3D but only a heart structure, not with cells or blood vessels. the potential for the engineering of customized fabrics and the confirmation of organs in the future, "said Tal Dvir, the principal author of the research published in the journal Advanced Science.

 

This heart took the fat tissue of 'printing' patients. While the cells were converted into a pluripotent stem cell, the extra-cell matrix (MEC), the three-dimensional cellular network (MEC), was used as a ink in a custom hydrogel.

 

According to Dvir, the specific "native" material of the patient is "essential" for the success of tissue and organ engineering.

 

"The biocompatibility of the engineering materials is essential for the elimination of the risk of implantation, which compromises the success of these treatments. Ideally, biomaterials are the biochemical, mechanical and topographical characteristics of the patient's tissues, which have resulted in thick, bulky heart and 3D infusions with the immune properties of the patient. which are totally compatible with cellulose, biochemical and anatomical ".

 

His team prepares to teach the printed heart in the laboratory and act as a normal heart. Then, they want to transplant the heart printed on 3D models of animals. "We need to develop more of this printed heart, the cells have to be able to pumping capacity, now we can shrink, but we must work together. Our hope is to be successful and to test our effectiveness and effectiveness", he concluded.
