Old mill town aims to become manufacturing center of human organs

However, mass-manufacture of organoids is definitely a thing that can be worked on today. Functional organoids for kidneys and livers might be able to replace many transplants, as you can in principal deploy them in volume, stick them onto and into the existing kidney or liver and they will help. The studies of transplantation have been done in animals, and they work. The same goes for the thymus, possibly lungs, heart muscle, and a variety of other tissues in which functional small sections or thin sheets can be grown from a patient's cells.

The idea would be to build an organoid manufacturing business, and by the time it gets large someone will have solved the blood vessel network problem, and you move on to organs at that point.
