In recent years, scientists have used 3-D bioprinting to make implantable skin, blood vessels, and heart and liver tissues. They can also print porous scaffolds that are loaded with stem cells and implanted in the body, where they form new tissue. These printed tissues could help regenerate damaged skin and cartilage or patch diseased heart and lung tissue, but they must be surgically implanted.
