Cloning Body Parts: It used to be done, but in the current era is obsolete twice over; first, replaced by organ printing tech (basically, 3D printers for organs), and second, by healing vats and having things built by medichines in situ. Hospitals and clinics probably have some organ printers lying around for special cases, but revolutionary as it was when it was first developed, organ cloning is now strictly for museums.
