Scientists have grown cartilage tissue in the shoulder joint of the robot.

It imitated the natural movements of a person, and this allowed the cells to grow and develop rapidly. Artificial cartilage can be used in medicine to model joints and tendons. During growth, it must be constantly stretched and bent. Previously, automatic devices that stretched the tissue were made right in the bioreactor, but in the end, real cartilage was still not obtained - strong and elastic. Scientists approached the problem in a different way. Instead of conventional devices, they used a robotic arm. The growing cartilage tissue was placed in an artificial shoulder for two weeks. The robot imitated human movements for half an hour a day. Under such conditions, the cells began to grow faster.
