A group of American scientists was able to implement in animals living tissue produced by a printer 3 Dimensions. A work developed over the last 10 years and represents a breakthrough in regenerative medicine.
The three-dimensional printer uses cells suspended in a gelatin solution, which can print cartilage, pieces of bone and muscle .
researchers from the Wake Forest Institute for regenerative Medicine printed fabric shaped ear, which was implanted in rats and eventually convert into functional tissue.
Nuno Neves, researcher 3B Group “s (biomaterials, Biodegradable and Biomimetic) at the University of Minho, speaks a giant step.
” the possibility of being able to print a fabric-shaped ear, in this case, who developed cartilage similar to what we have in the ear. This was done in the laboratory and validated in animal models, which allows to foresee that in the future it will be possible to develop this type of potential application structures in patients. “
The Integrated Textile Printing and Organs uses materials plastics and biodegradable to create the shape of the fabric and the gel that keeps the cells alive long enough to develop into functional tissue.
According to the Portuguese investigator, “which was shown in this publication is that it is possible to combine biomaterials with cells maintain viable cells within the biomaterials, such that after cultivation this structure in vitro and after being implanted in an animal model, the cells initially there put survive and can develop a similar tissue to tissue that have the fabric we want to develop. “
to Nuno Neves we may be one step closer to producing organs.” it is a demonstration that the technology is developed to the point where we can dream it, from today to tomorrow, we can make organs to implant in patients who need them. “
this research was funded by the Regenerative Medicine Institute of the United States that want to apply this technique in wounded soldiers, given the scarcity of donors.
The study was published in the British journal Nature.
