If this research is successful, it may then reduce the need to research and sacrifice human embryos.

Let me write this down in a vibrant color.

The embryos.

So why should you care? Bone marrow is a very rich source of adult stem cells.

And divides anew every 12 to 15 hours.

Embryonic stem cells have occupied center stage, chiefly because of their pluripotency that is their ease in differentiating into a variety of different cell types.

But adult stem cells are not embryonic stem cells.

Since it's so pluripotent, it can become germ plasm.

So at least my take on it is if you're against and I generally don't want to take a side on this, but if you are against research that involves embryonic stem cells because of the destruction of embryos, on that same, I guess, philosophical ground, you should also be against in vitro fertilization because both of these involve the destruction of zygotes.

But there are more important things that are already occurring embryo screening.

The whole process of differentiation is actually fascinating, and we'll talk a lot more about that when we talk about stem cells, embryonic stem cells, and maybe we'll even talk about the debate of it.

look like that, and then my embryoblast is going to look like this.

How are the embryos?

And at that time, stem cell research had gained momentum, following the isolation of the world's first human embryonic stem cells in the 1990s.

So sometimes you'll say morula, and you go to blastula.

These are animals like alligators and most turtles.

Let me write those words down.

45 Days

They discovered that adult cells, taken from you and me, could be reprogrammed back into embryonic like cells, which they termed IPS cells, or induced pluripotent stem cells.

So the debate obviously is when you start an embryonic stem cell line, you are destroying an embryo.

But it doesn't have to just infect somatic cells, it could infect a germ cell.

So eventually all of these turn into blastocysts.

The zygote happens or gets created and starts splitting up the morula, and then it keeps splitting and it differentiates into the blastocyst, and then this is where the stem cells are.

In the immortal germ line of human beings that is, the eggs that sit in the ovaries they actually sit there in a state of suspended animation for up to 50 years in the life of each woman.

On delivery, 50,000 more for each viable embryo.

The embryos need to mature in a safe environment.

Beginning of the primitive vertebrae

While we're talking about mammals, especially the ones that are closely related to us, the stage is the blastocyst stage, and the real differentiator is when people talk about just blastula and blastospheres.

You're going to kill this developing embryo, and that developing embryo had the potential to become a human being.

Now, it can be a very confusing topic, because a lot of times in a lot of books on biology, you'll say, hey, you go from the morula to the blastula or the blastosphere stage.

All vertebrate embryos are inherently female, anyway.

They may or may not be perfectly viable, but you have these embryos that have the potential, just like this one right here.

A very non intuitive spelling of the coel part of blastocoel.

And this mass of cells, we can start calling it, this right here, this is referred to as the morula.

So these all become zygotes, and then they allow them to develop, and they usually allow them to develop to the blastocyst stage.

Let me scroll down a little bit.

And then again.

Fertilization.

As we speak, the world's first human embryonic stem cell trial for spinal cord injury is currently underway following the USFDA approval.

This is an extremely new field.

Do you know what he's doing with the embryos?

The inner cells pick a suitable color.

Recommendation 2

They have a blastocoel in the center, which is this area of fluid.

Birds have basically rudimentary tails.
