It's not just any cell in the body.

From Conception to Birth Oocyte

The most exciting thing for Bob Lanza is the ability now to take any kind of cell with induced pluripotent stem cells and turn it into germ cells, like sperm and eggs.

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.

I think we have found the problem. Your ovarian follicles are still immature.

Fifty communicable diseases like to travel in human shit.

That's the egg, and we all know how this story goes.

And the cells that have a haploid number of chromosomes are our gametes, which are sperm cells for men, and ova, or egg cells for women.

And the germ cells I'll just write it here, just so you get a clear for a male, that's the sperm cells, and for female that's the egg cells, or the ova.

Now, that first cell that had the potential to become me, it was a product of fertilization, of an egg from my mother so an egg from my mother.

A somatic cell, a body cell, was taken from its body, gestated in the ovum of a cow, and then that cow gave birth to a guar.

So this very first cell that was created from this fertilized egg, this is called a zygote.

Now, in the case of humans, the diploid number is 46, so N is equal to 23.

This would be sperm.

So that's a gamete and this is a gamete.

For each homologous pair, I'm either going to contribute the one that I got from my mother or the one that I got from my father, right?

And so we see a mushroom here sporulating.

Oeufs. Un oeuf, des oeufs.

You can change the cells in your body, but what if you could change the cells in your offspring?

I actually chased the mycelium, when it stopped producing spores.

And I'll draw the sperm much larger than it is normally relatively to the egg.

(Laughter)

I plan to integrate the Infinity Mushrooms into a number of objects.

Where we left off after the meiosis videos is that we had two gametes.

In a female, they would be involved in the ovaries.

Just as an aside, this unification, this fertilization that occurred from this sperm cell to this egg cell, so it essentially penetrates into this egg cell and it creates this zygote, which is a fertilized egg cell from my mother, and this contains all DNA from both my father and my mother.

And place cells also get this kind of path integration input from a kind of cell called a grid cell.

In fact, it's one of the biggest problems with chemotherapy today.

What we did is something called somatic cell nuclear transplantation.

The ostrich egg is a single cell, and it can grow up to five pounds.

In some cases, another species like the North American Leopard Frog showed that males exposed to atrazine grew eggs in their testes.

Let me draw the sperm.

When I was a lad I ate four dozen eggs Every morning to help me get large

Sons of Gondor, of Rohan, my brothers!

So a fertilized egg or even just a regular somatic cell or a body cell will have a diploid number of chromosome, while a sex cell, and I'll be a little bit clearer about that in a second, will have a haploid number of chromosomes.

We took the eggs of a related species, a living frog, and we inactivated the nucleus of the egg.

Recommendation 2

So that very first cell that was essentially my mom's egg fertilized by a sperm cell from my father, that was a zygote, and as soon as it's successfully fertilized, it has 2N, or it has the diploid number of chromosomes in the case of humans, which I believe I am one of them.

Hey, listen. I, I got a big problem. I totally just lied to Pink.

Eggs?

They can't do it naturally, so what they do with this thing is they take a spoon, take some cells out of an adult gaur's mouth, code, take the cells from that and insert it into a fertilized cow's egg, reprogram cow's egg different gene code.

Let me do that Y chromosome in a separate color.

The fundamental forms of ferns followed,

And then we took the dead nucleus from the dead tissue of the extinct frog and we inserted those nuclei into that egg.

Think of it as beginning to program stuff for specific purposes.
