There have been lots of great questions — I think I’ve most enjoyed the questions about the intersection between science and religion as well as the questions about my own research on retinal stem cells (because they were the easiest for me to answer).
Hi Jonah,
the best question has to be: if a stem cell got into a fight with a blood cell, who d’you reckon would win?
That’s a tough one because a stem cell can be a little like the Mystique character in X-men – it can turn into any of the other cell types. But then a white blood cell can be pretty nasty! It can secrete free radicles and enzymes that can destroy other cells, like explosives, but not only that, they will gobble up the baddies and get loads more white cells to come along to do the same. But ultimately, I have to give it to stem cells because stem cells can also replicate themselves so they can theoretically become a whole army of white blood cells!…
