Okay kiddo, so you know how our body is made up of many different types of cells, like skin cells, nerve cells, and blood cells?
Well, sometimes scientists want to make other types of cells from one type of cell. This is where STAP cells come in.
STAP stands for "stimulus-triggered acquisition of pluripotency". Pluripotency means the ability to become any type of cell in the body, like a stem cell.
Scientists found that if they took a normal adult cell, like a skin cell, and exposed it to some special chemicals or stress, it could turn into a pluripotent cell - a STAP cell.
This is really exciting because before STAP cells, scientists would have to use embryos or special techniques to make pluripotent stem cells. But now, they can make them from adult cells really easily!
This could help with all sorts of medical research and treatments. But it's still a new and controversial topic in science, so we'll have to wait and see what happens next.
