Fat derived stem cells are adult stem cells.

We're excited. We've got to get past this point.

The results revealed that in environment A, the cells formed muscle, in environment B, the cells formed bone, and in environment C, the cells formed fat cells.

And then this bubbling, this membrane bubbling, is the hallmark of apoptosis in this cell.

This released oxygen into the atmosphere.

So I had three different environments, yet genetically identical cells in each dish.

So by the end of telophase I, you have the actual cytoplasm splitting during telophase right there, and the nuclear envelope is forming.

Now, at the same time telophase is happening, you also normally have this cytokinesis, where this cleavage furrow forms, where essentially during telophase, these things are getting pushed further and further apart by those microtubules so that they're already at the ends of the cell, of the cytoplasm of the cell, and you can almost view them as pushing on the sides to elongate the cell.

And here is the limitation adult stem cells are mature cells, and, like mature human beings, these cells are more restricted in their thought and more restricted in their behavior and are unable to give rise to the wide variety of specialized cell types, as embryonic stem cells can .

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.

If we can somehow encourage these molecules to talk to each other and make the right shapes and compete, they will start to form cells that will replicate and compete.

They control how the cells grow and differentiate.

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

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

little, itty bitty creatures called cells.

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 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.

They've got great potential but haven't yet entered clinical trials.

What kind of changes happen?

They were changing shape.

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

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

He generated neurons from these induced pluripotent stem cells from patients who have Lou Gehrig's Disease, and he differentiated them into neurons, and what's amazing is that these neurons also show symptoms of the disease.

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.

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.

Cell division

Cell radius

They were developed in Japan pretty recently.

From Conception to Birth Oocyte

Fuel cells.

Kecyte and... at that rate, you couldn't possibly maintain cell regulation or differentiation.

Some cells in the fetus, actually receive signals to self destruct here the developing hand grows has an enormous bumble of cells.

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

And that's your ancestor.

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

And we prefer cells that will not reject and will not form tumors.

Epigenetic marks can be influenced by the environment.

(Laughter)

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

They get pulled apart even more.
