cells and their properties. 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.
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.
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.
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.
Thank you very much.
