Cell Differentiation: The Search for the Organizer (clip)

Embryologist Hans Spemann, in a series of brilliant experiments he thought of as conversations, induced a tiny embryo to hear certain questions. Finding additional clues in embryologist Walter Vogts fate map, Spemann discovered the organizer — that group of cells that differentiates first and then induces the differentiation of other cells around it. A Coronet release. 15 minutes, color.
