Helen Blau and Margery
Fain first met at Harvard University as Ph.D. students. Helen became a
world-famous stem cell scientist and is a Professor and Director of the
Baxter Laboratory for Stem Cell Biology at Stanford University. Margery
became a research biologist, then an illustrator for scientific
textbooks and author of childrens' books. Reconnecting many years later
in Paris, Helen and Margery were inspired by their grandchildren to
create this book to amaze and delight kids everywhere about the
extraordinary things stem cells can do in our bodies.
