Description

When your skin is cut, it heals. When you break a bone, it mends. How does this happen? Because your body is made of cells, including a very special kind called stem cells. They live in many places in your body, such as skin, muscles, bones, and blood. And when any part of your body is injured, stem cells jump into action to repair the damage. This book contains a tale told in rhyme about how stem cells work and what scientists are doing to help them work even better, especially as people get older.

About the Authors

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.
