Cellular Specialization
In this podcast
Paul Andersen explains how cells differentiate to become tissue specific. He also explains the role of transcription factors in gene regulation. The location of a cell within the blastula ultimately determines its fate. The SrY gene is an important external stimuli in human development. The heat shock factor is also discussed as an example of an environmental simuli.
