Despite the progress made in recent years, this technology still faces many obstacles before producing usable tissues and organs, researchers said, taking part in a new scientific study on the reality of organ manufacture using biometric 3D printing and its future prospects.

Organ bioprinting
3D Biological Printing is a highly advanced manufacturing platform that allows tissue - and vital organs at the end - to be printed from cells. This could open up a new world of possibilities for the medical field, while directly benefiting patients who need alternative organs.

Instead of waiting for a suitable donor with the possibility of the body rejecting the transplanted organ, 3D printing allows patients to have an organ specifically designed to replace damaged or diseased organs.

But despite the advances that this technology has made over the past two decades, it still needs great strides in order to produce complex 3D tissue designs, according to a new scientific study.

In-depth diagnosis of development
According to the new research paper published by researchers from Taiwan and Singapore in the "Progress in Polymer Science" journal last October, tissue culture techniques in particular require rapid progress to overcome basic obstacles, particularly in the maturity of 3D cells that are biologically mixed and biologically mixed in functional tissues .

In this paper, the researchers made an in-depth diagnosis of the development in this field and analyzed the techniques of bio-printing and the progress made in the development of bio-ink and the implementation of new strategies for bio-printing and tissue maturity.

They also paid particular attention to the role of polymer science that complements 3D bio-printing, to overcome some major barriers in the field of organ printing such as the implementation of biomimetics, vascular and anatomically appropriate 3D biological structures.

The researchers considered that the use of complementary strategies such as the development of biometric ink is crucial to ensure the maturity and aggregation of vital tissue structures.

Ambitions for the next two decades
Although it is currently possible to manufacture tissues or human organs that can mature into tissues that contain vessels that are partly usable, this industry is still late in the dynamic printing of tissues or human organs due to the complexities of the tissues and the maturation process and the lack of an appropriate medium for the multiplication of multiple types of The cells add to the need for more tissue conditioning before implantation.

"Although 3D biological printing is still in its early stages, the remarkable leap it has made in recent years indicates the ultimate reality of functional organs implanted in the laboratory," said researcher Chua Chai Kai of the University of Technology and Design in Singapore and lead author of the paper. Medicine we must overcome the technical challenges in the textile industry. "

Important achievements have been made in recent years in this field, including what scientists announced earlier this year what they said was the first three-dimensional printed heart, made of human tissue containing blood vessels, ventricles and chambers.

Academics and startups in this branch of bioengineering believe that replacing the skin, liver and bladder can become a clinical reality for the next two decades.
