6th July 2009 – From a Single Cell to a Complete Animal

Dr David Tannahill of Cranfield University will talk to us about how genes work in the development of an embryo. How they get switched on and off in different ways in different cells.

Each cell contains all of the information to make a complete human being and yet some “decide” to become a fingernail whilst others become brain cells. What makes them do that and in such an ordered fashion that the end result works? What about stem cells? Why haven’t they decided what to be yet? If they haven’t decided yet, why is it so difficult to get them to “decide” to be what we want them to be? What do we still have to do to unleash the medical benefits of stem cells?
