US scientists announce 3D heart printing breakthrough
Scientists in US have successfully built functional heart parts out of collagen using a 3D bioprinter, a breakthrough they say could one day create entire organs.
Their technique, which was described in the journal Science, replicates the body’s own complex biological scaffolds that provide the structure and biochemical signaling organs need to function.
Collagen, which is an ideal biomaterial for the task since it is found in every tissue of the human body, starts out as a fluid and attempting to print it resulted in puddle of jello-like material.
The technique could one day help patients awaiting heart transplants, but it will need to validated through animal testing and eventually human.
