    00:00 Another aspect we can consider is that development does not stop at birth. So we already know the infants and children will go on developing.

    00:11 It will be fair to say that development is a lifelong process. So if we view it as developmental biology, it continues all the way through until such times as you get old and die. So it will be fair to call aging a kind of development as well. So obviously understanding the nature of the events underlying ageing might be a valuable medical ability as well. And we know for instance that cancer cells are effectively immortal. So the question of how they become like that would be valuable to answer and we know the embryonic stem cells are effectively immortal as well. So there's something about very early embryonic cell that shares this immortality and therefore perhaps that can offer clues to the aging process and indeed death as well.

    00:59 So, obviously you can see there are some extremely important features about embryology that could be very important for medicine in the future. Even notwithstanding that, developmental defects are sufficiently common to be a major problem in their own right. And the early stages of development give us valuable clues towards understanding the control of reproduction.

    01:22 If we could understand how cells become different from each other in different environments during development, it gives the possibility of using stem cells to create all kinds of organs that replaced as they become defective for some reason in the adult. That is here for this lecture.

    01:38 Thank you very much.
