3-D printed ovaries produce healthy offspring in mice
This is a good demonstration of the point that artificial organs don&#x27;t have to be the same as the real thing, they just have to be similar enough for the subset of tasks desired.<p>This is especially true for chemical (liver) or cell (thymus) factory organs. Just because the research community can&#x27;t yet manufacture blood vessel networks needed for large organs doesn&#x27;t mean they can&#x27;t use fully or mostly functional organoids to produce benefits. It is possible in principle to patch a diseased liver with many organoids, or put thymus organoids into lymph nodes, and so forth.<p>This sort of thing will get underway in earnest if there isn&#x27;t any real movement on the blood vessel network problem within the next few years.
