Cell division

Well, so what I read on WebMD

That's their job.

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.

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

I'll nicely demonstrate that for you. (Laughter)

So, we took the red cells you see the red cells are surrounded by blue, other cells that squeeze them, and behind it is material that people thought was mainly inert, and it was just having a structure to keep the shape, and so we first photographed it with the electron microscope years and years ago, and you see this cell is actually quite pretty.

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.

It's also simpler when you go into eukaryotes like ourselves you can just pop out the nucleus and pop in another one, and that's what you've all heard about with cloning.

Or if we're going to use larger structures to replace larger structures, we can then use the patient's own cells, or some cell population, and the biomaterials, the scaffolds, together.

In the case of a male, these would be sperm cells.

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

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

In other words, we're not literally replacing the components of the retina.

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

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

Basically, a human body is a conversation going on, both within the cells and between the cells, and they're telling each other to grow and to die, and when you're sick, something's gone wrong with that conversation.

This is the whole cell.

I shouldn't say cell wall.

Եթե մենք գործ ունենք բուսական կամ ոչկենդանական բջջի հետ մենք ունենք այսպես կոչված բջջապատ, որ տալիս է բջջին որոշակի ամրություն

They all came from one unique embryonic stem cell or what initially was a blastomere.

Fat derived stem cells are adult stem cells.

It's kind of like an evolution machine.

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

So this is my body cells.

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

And, there are other frequently dividing cells in your body

It remembers that it's cancer.

Cell radius

They were developed in Japan pretty recently.

Fuel cells.

That turns out to be a big deal because now you can take, not just mouse cells, but you can human skin cells and turn them into human stem cells.

But, when cells join together, with more than one cell like itself to perform a similar function, it's no longer a unicellular organism.

From the way it's bound to her neurons, I'd say it's been there since she was a child.

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

And if this continues the toe cell would die.

There's a class of cells, a fairly small cell, an inhibitory cell, that quiets its neighbors.
