Description:
What if some of your cells were not your own? What if they once belonged to someone else?
Part mind-bending medical mystery part cutting-edge science Hidden Guests uncovers the astonishing phenomenon of microchimerism: the presence of foreign cells inside our own bodies. The incredible story of how those cells got there and what they do once they arrive might change everything we know about the immune system, lineage, and identity.
We are all told the same story as children: that we grew from a single cell into a human, that all of our cells came from the first fertilised egg, and that we have one distinct genetic code. But scientists are beginning to challenge that story.
The discovery of microchimerism shows that not all our cells are our own some of them migrated from other bodies. How did they get there? Scientists are still studying their journey, but today we know cells are exchanged in pregnancy, through transplants and blood transfusions, and possibly even through sex. But what does this mean for our daily lives is it really such a big deal if someone else's cell turns up in our bodies? The answer is, as author Lise Barneoud shows in Hidden Guests, that the implications could be earth-shattering.
In Hidden Guests, Barneoud interviews doctors, researchers, and medical experts at the forefront of microchimerism research. She interweaves their fascinating discoveries with the shocking human stories of microchimerism including:
- The story of the mother who gave birth to the genetic children of he
