Bioprinted 'play dough' capable of cell and protein transfer

Scientists have developed a new technique allowing the bioprinting at ambient temperatures of a strong paste similar to 'play dough' capable of incorporating protein-releasing microspheres. The scientists demonstrated that the bioprinted material, in the form of a micro-particle paste capable of being injected via a syringe, could sustain stresses and strains similar to cancellous bone -- the 'spongy' bone tissue typically found at the end of long bones.
