Meet Henry, the Stem Cell. Cells are the building blocks of life, and make up your entire body from your toes to your brain. Most cells can only develop to do one job, but Henry is a “special” type of cell with magical powers. Henry’s powers include the ability to transform himself into many different types of cells to help people who need him. He can also make a lot of copies of himself.

But what exactly can Henry do?

Replace damaged cells in the heart so that Billy’s grandpa’s heart can still beat after he has a heart attack.

Turn into cells in one's eyes, so Hannah who lost her vision can see again.

Turn into neurons so Sally who has MS can still run and play soccer with her friends or help AJ’s grandpa with Alzheimer's remember who AJ is .
