Researchers have been using 3-D–printing techniques in hopes of developing tissues that can be transplanted into humans. Some printed tissues, such as skin and bone, are already being tested in humans, while many others are much earlier in development.
Bone – Scientists have 3-D printed scaffolding that is seeded with living tissue that grows into bone. While several preclinical trials are underway, one patient with tibial osteomyelitis, an infection that damaged 36 centimeters of his leg bone, successfully received the transplant in 2017 and is now walking. Clinical trials are planned.
Cornea – A company called Precise Bio reports it has completed initial safety studies in animals of 3-D printed corneas to treat eye injuries, defects, and infections that cause permanent damage. The company has progressed to further preclinical trials in multiple animal models, and expects to begin clinical trial next year.
