ScienceDaily (2016-03-16)—Arthritis and injuries take a huge toll on the knees among people young and old alike, often requiring surgery, including knee replacement. With the rise in 3-D printing, however, and 3-D bioprinting in particular, researchers are finding it possible to use bioink (ink composed of human cells as well as polysaccharides from plants or bacteria) to print living cells that can be implanted to heal knees, ears, and noses. Thus far, 3-D printed cells implanted in mice successfully produced cartilage. What’s next? Read more
