This tissue that is of particular interest to a biologist named Gemma Evans because it kind of turbocharges this entire process.

The uterus, of course, is the womb, and the endometrium is its lining, the sort of safe, nurturing space for a fetus to hang out.

So every month, the uterus builds the lining up, and then if no fertilized egg shows up, it flushes all that work away, kind of like sloughing off layers of skin.

So the endometrium creates a wound, essentially.

It heals not in two to three weeks like the rest of the body, but in three to five days.

And usually it heals without scarring.

So normally when the body does kind of a rush job like this, it has to make some sacrifices.

It can build up scar tissue instead of regular skin.

And that scar tissue can't always do what the original tissue could do.

In the case of the endometrium, though, the repaired tissue is just like the original.

This process is so quick and so impressive that I got Gemma and some of her colleagues thinking.

If she could harness those properties, it could potentially help a lot of people, diabetics whose wounds heal really slowly, people who have vascular diseases, even patients with burns.

So this is Unexplainable.

I'm Bird Pinkerton.

And this week, Gemma Evans tries to figure out if there's a way to translate the uterus' super healing powers to the rest of the body.

Going into all this, Gemma had a big hunch.

Because the healing that's happening in the uterus is happening while the uterus is bathed in menstrual fluid.

This stuff that we also call period blood that is basically sort of a super complex mixture of tissues and proteins and cells and other stuff.

And so Gemma's hunch was that menstrual fluid might be what's helping the uterus heal so fast.

And also that menstrual fluid could help other wounds heal faster too.
