Quite a while ago now, but I used to work at a tissue engineering lab in London. I was interested in how techniques from procedural design and architecture could be brought across, as actually the design of many of the TE scaffolds seemed very crude.

Blood vessels grow according to growth factors that are released in response to hypoxia, I wanted to try and model them as a space colonisation. I never quite got around to producing the actual structures, but some more details here:
