Human retinas grown in a dish explain how color vision develops

Biologists at Johns Hopkins University grew human retinas from scratch to determine how cells that allow people to see in color are made. The work lays the foundation to develop therapies for eye diseases such as color blindness and macular degeneration, and establishes lab-created "organoids" as a model to study human development on a cellular level.
