In this image, undifferentiated stem cells of the zebrafish eye (red) begin to differentiate (purple) to become functional retinal neurons. This carefully controlled process continues throughout the entire life of a zebrafish.

This image appears in the Koch Institute Public Galleries through a partnership with Wellcome Images, a UK-based leader in the collection and public display of scientific images. Visit Wellcome Images on the web at
