I think that the best explanation of what a stem cell is, is it's a cell that can make copies of itself, but it can also differentiate into more mature cell types.
So it could make more copies of itself, but it could maybe turn into a muscle fiber or it could turn into a red blood cell or a kidney cell, fill in the blank.
in the body and they play different roles in basically maintaining homeostasis.
So I guess to get back to, you know, the beginning here, most people, when they hear stem cells, I think they think of embryonic stem cells.
So these would be like from the early, early development, these cells can become anything in the body, right? And that's why they have so much promise clinically, but really people don't use them or study them much anymore because we have alternatives to them.
But what I would say we think about, let's just think about like as an adult human being, right? You're sitting here, you have stem cells that are making blood constantly in your body.
Those are located in your bone marrow, and they're only responsible for making blood.
We have other stem cells that are like in the fat layer underneath your skin.
And those are basically important for making fat, bone, muscle, skin cells, things like that.
So you may not know, but the intestinal lining of your gut is turning over constantly.
And basically there's these really cool like little crypt structures and the stem cells are down in the bottom of the crypt and they make new cells and the cells come up to the top of the crypt and then they get sloughed off and they get washed away.
And the reason they make different things is because they're in different locations and they're getting different signals from your body.
