When it comes to the topic of embryonic stem cells, there's lots and lots of controversy over this.
00:09
So first, let's identify how this comes about.
00:13
So when it comes to embryonic stem cells, a human cell is going to start off as just a single cell, right? when fertilization takes place where a sperm cell is going to penetrate an egg cell and fertilize it, which begins a process of a baby being formed.
00:31
Now, once this takes place, cells are going to be constantly dividing over and over again through the process of meiosis, right? because we know that that's how the sperm cell and the egg cell took places through the process of meiosis.
00:43
So cellular division is going to be taking place over and over to produce a baby.
00:48
So here in this first diagram, we can see that taking place how fertilization is taking place here.
00:53
And then as time goes on, this is what the end result is the baby.
00:58
So as this is taking place, an embryotic stem cell is going to be found in the same.

The blastocyst right here.

So this is five days old, an embryo...
