Five-Year-Old Mini Brains Can Now Mimic a Kindergartener’s Neural Wiring. It’s Time to Talk Ethics. (singularityhub.com)

Among pressing ethical concerns are whether brain organoids can feel pain or become conscious—and how would we know?

It links to an article about brain organoids with blood vessels:

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!

Also, note that article's 8 years old and way out of date.
