At least potentially, they are doing nothing.

Like, it is possible that my cells are just like...

The tchotchkes that you love to collect, right?

Like your little figurines that don't really do anything.

They're just kind of there.

It's possible that my cells are just the equivalent of that.

Like you have some tiny little cell-sized tchotchkes of me inside of you.

Yeah.

You bought granite?

Like, you can find granite on the ground.

Well, but this was polished.

So, again, there is a possibility that these cells are just hanging out, like...

polished granite, but researchers have some good reasons to think that these cells are potentially doing other things.

They found cells from the baby in the parent's scar tissue, essentially.

Uh-huh.

And again, it's possible that they're just sort of

randomly there, right?

Because as Amy was saying, these studies in humans aren't super firm evidence because we don't know what they would be doing to heal a body.

It's not clear that there are necessarily lots more fetal cells in this scar site than anywhere else in the body.

If you just sort of step away from humans for a second, there is some more definitive research that has been done in mice.
