In an incredible breakthrough, researchers used a patient’s own cells and other biological materials to “completely match the immunological, cellular, biochemical, and anatomical properties of the patient.”
This is a big deal – until now, only simple tissues that lacked blood vessels have been 3D-printed.
The lead researchers issued a statement, and it’s easy to read their excitement between the lines.
“This heart is made from human cells and patient-specific biological materials. In our process these materials serve as the bioinks, substances made of sugars and proteins that can be used for 3D printing of complex tissue models. People have managed to 3D-print the structure of a heart in the past, but not with cells or with blood vessels. Our results demonstrate the potential of our approach for engineering personalized tissue and organ replacement in the future.”
