The tiny, human-derived “brain organoids” grown in dishes, grew two “symmetrical optic cups” which apparently mirror the development of eyes on human embryos. If this wasn’t horrifying enough, the eyes appear to be at least partially functional, as they respond to light by sending signals to the rest of the brain tissue. The organoids are made by harvesting adult human stem cells that have the potential to morph into many different types of tissue. The scientists in this instance “coaxed” the cells into creating brain tissue, as using real human brains for an experiment of this type might not be considered ethical. Is this a new move to help in fighting neurodevelopmental disorders ?
