Cell division

celermitosis.

Out comes the liposuction fluid, and in this case, the stem cells are isolated and turned into neurons.

So if I start off with a diploid cell, and that's my diploid cell right there, this would be a germ cell.

You probably know, if you've been paying attention to some of the science literature that you can now take a skin cell and encourage it to become a liver cell or a heart cell or a kidney cell or a brain cell for any of us.

It has not experienced cytokinesis, which we will talk about in a few moments, but that's the process of the actual cytoplasm of the cell being split into two different cells.

So certain genes are expressed in certain parts of the body, but every one of your body cells, and we call those somatic cells, and we'll separate those from the sex sells or the germs that we'll talk about later.

But what does a cell do?

Wait a minute. How do you interrupt the cellular mitosis?

So in a male, you have some germ cells, so some of these cells turn into germ cells.

Mitosis occurs in pretty much all of our somatic cells as our skin cells replicate, and our hair cells and all the tissue in our body as it duplicates itself, it goes through mitosis.

Each one plays a particular role a heart cell, a muscle cell, a brain cell.

The observation that stem cells, as master cells, could give rise to a whole variety of different cell types heart cells, liver cells, pancreatic islet cells captured the attention of the media and the imagination of the public.

And so if this germ cell undergoes meiosis, and I'll do a whole video on the mechanics of it, instead of two cells, it'll actually produce four cells that each have half the number of chromosomes in them, so these cells are haploid.

And as we go smaller again, about ten times smaller than that, is a cell.

And the reason is that cancer, like every cell in the body, places little molecular bookmarks,

Let's look at a healthy liver cell, a healthy hair cell, and a cancerous cell.

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.

No thanks, I'd actually rather store this energy.

Fat derived stem cells are adult stem cells.

By the end of telophase in mitosis, you also have this process of cytokinesis, where this cleavage furrow forms and deepens, deepens, deepens until the cytoplasm is actually split into two separate cells.

But even now, 2011, there's still certain cells that we just can't grow from the patient.

So it just starts splitting into two more cells that are and actually, let me do it this way, just because the actual way it works is right when a cell is split, the cells that it splits into aren't that much larger than the original one.

It gets bigger, and that's during the G2 phase, so it's just growing more.

They were developed in Japan pretty recently.

From Conception to Birth Oocyte

Fuel cells.

This is in the S phase of interphase.

They control how the cells grow and differentiate.

In these cells, the mission is to move blood around their body.

And that's your ancestor.

And what MyoD essentially does is, it causes cells to differentiate into muscle cells.

But, enough mutations can bypass the fail safes, driving the cell to divide recklessly.

For example, why is it that the mitochondria in every cell has its own DNA, totally separate from the DNA in the nucleus?

The centrosomes have gone to opposite sides of the cell itself.

So this is my body cells.

This is the whole cell.

I believe matter begets life

So, in the end, it is all about growth.

They get pulled apart even more.
