It's not science fiction: UC San Diego researchers are developing human organoids — miniaturized, 3D versions of an organ produced from reprogrammed stem cells in the lab. These models, sometimes called “mini-brains” or “organs-in-a-dish,” have allowed scientists to study biological functions, diseases and treatments more realistically and in greater detail.
So far this approach has been used to produce the first direct experimental proof that the Zika virus can cause
severe birth defects, to repurpose existing HIV drugs on a rare,
inherited neurological disorder and to create
