Ok it sounds like they got functioning vessels after xenografting into mice (which has its own issues) and it mentioned connecting to micro fluidic chambers in the future for full ex vivo, but they don't have a functioning model for that yet. It's a very interesting and promising area of research but with practical lab work nowadays it's just not feasible. I hope they're able to get a full ex vivo model working soon though, that would be really exciting!
