What's the deal with stem cell research?

I know that it's supposed to cure everything ever.

I know that it's very controversial.

I don't understand how it's supposed to cure everything ever.

What are these stem cells?

What do they do?

Why are they so special?

Stem Cells

Stem cells are special because, unlike the cells of your body, they can become any sort of cell they want to (which is handy when you need to produce an entire human body from two microscopic, often unrelated zygotes). Once a stem cell becomes a liver cell, that liver cell won't change back into something different, like a skin cell. Liver cells divide into liver cells divide into liver cells divide into liver cells, etc. However, bad liver cells also only replicate into bad liver cells. Stem cells (which, mostly, only exist in the earliest stages of embryonic life) are important because if you're born without a liver, or your liver cells have a mutation, because you can start with a "blank" cell and set it on the course to become anything, like "good liver cells."
