They are pretty rugged, you're constantly
#STEM CELLS SKIN#
Of our skin that we can see and that we can touch, right? And it's made of these waterproof, pretty rugged epithelialor skin cells and interestingly, although And they can't repair everything, but, there's a lot of every day repairs that can happen because of our stem cells. Trillions of specialized cells, and the somatic stem cells are used as sort of a repair system for the body, replenishing tissues So, the embryonic stem cellsĪre used to build our bodies, to go from one cell to Embryonic stem cells that we just saw and somatic stem cells whichĪre found in every person. We can find stem cells, here in the developmental structures? We used to think so, but, it turns out that in mammals, there are And actually, if you ever hear anyone talking about embryonic stem cells, these are the ones they're referring to, these ICM stem cells. So, it's kind of incredible to think that every single cell in your body can trace its ancestry back to this little group of stem cells, here. These inner cell mass pluripotent stem cells can differentiate into any of the more thanĢ00 different cell types in the adult human body when Pluri meaning several and potent referring to these stem cells' ability to actually do this differentiation. And what they can do as stem cells is they can specialize into Little bunch of cells that go on to become the embryo. This little grouping of cells down in here, referred toĪs the inner cell mass. And here, things start to getĪ little bit more interesting. The blastocyst stage, this hollow ball of cells So, the zygote starts to divide, right, by mitosis until it reaches When sperm and egg fuse because that's really where our stem cell story kinda begins.
And let's actually startīack at the zygote, here, the cell that results So, let me show you what I mean by that over the course of this video. You got more and more committed down a certain pathway, and the decisions that you made moved you further and furtherĪlong this pathway, right? Well, it turns out that stemĬells operate in a similar way, going from unspecialized You had the potential to specialize into all sorts of different careers, and as you got a bit older, You could decide to be a pilot, or a doctor, or a journalist.
When you were still anĪdorable little baby, you were just bursting with potential.
