Rhinoplasty / the cosmetic surgery industry depends on cartilage from cadavers in some countries. In other countries cadaver cartilage is avoided due to the potential for reabsorbing and degrading in the patient's body, and therefore cartilage can be taken from the patient's own ribs.
I'm not sure if this specific breakthrough in the article would be suitable for shaping the nose permanently. But last time I checked (10 years ago), there was a specific need for synthetic cartilage to improve patient outcomes.
