3-D Printing Tech Could Someday Make Replacement Ears a Reality

Athletes, the elderly and others who suffer from injuries and arthritis can lose cartilage and experience a lot of pain. Cartilage is a tissue which has very poor regenerative potential. Researchers are now reporting in Biomacromolecules, however, that they found a way to produce the “rubbery”  cartilage tissue with 3-D bioprinting and human cells that produce cartilage. The researchers say they have successfully confirmed their findings via an in vivo mice model. The development could one day lead to precisely printed implants to heal damaged noses, ears and knees.
