ByJill Rosen /PublishedOct 11, 2018 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, set for publication in the journal Science, lays the foundation to develop therapies for eye diseases such as color blindness and macular degeneration. It also establishes lab-created `organoids` as a model to study human development on a cellular level. `Everything we examine looks like a normal developing eye, just growing in a dish,` said Robert Johnston, a developmental biologist at Johns Hopkins. `You have a model system that you can...
