Right now, it's easier to scan than to simulate. That said, we definitely don't have the means to 3D print even relatively simple tissues, last I checked we are still limited to structures thin enough to be kept alive by oxygen diffusion. One of my open questions on this topic is: given we can cryopreserve small tissue without the freezing-damage problem, why can't we do a repeated process of: 1. cell culture tissue sheets that are ~1mm (or whatever) thick 2. cryopreserve each sheet 3. then assemble those sheets, still frozen 4. then thaw out as per normal procedure for cryopreserved organs Caveat: I have minimal knowledge of biology, this may be a stupid idea for a whole bunch of reasons I don't even know the names of. |
