A three-dimensional (3D) bioprinting technique developed by researchers at Canada's University of Alberta (U of A) can generate customized cartilage for use in restorative surgeries.
The team employed a specially designed hydrogel that is combined with cells harvested from a patient, then printed in a specific configuration captured through 3D imaging.
The material is cultured in a laboratory to become functional cartilage, which U of A's Adetola Adesida said can be ready for implantation within four weeks.
Adesida said with this technology, a patient "can go on the operating table, have a small biopsy taken from their nose in about 30 minutes, and from there we can build different shapes of cartilage specifically for them. We can even bank the cells and use them later to build everything needed for the surgery."
