Bristol University has produced a bio-ink that prints stem cells that develop into complex tissues like bone and cartilage. So true bioprinting is one step closer now.
At the moment, bioprinting is very much in the experimental stage and we still rely on the likes of titanium for knee and hip replacements. Bioglass, meanwhile, is showing great potential as a cartilage replacement and natural scaffold. Fully compatible bio-printed replacements would be infinitely better, however, and this development in the UK is seriously good news.
