Where are the kids?

And that waste could be all sorts of things, and one that kind of jumps to mind is carbon dioxide (CO2).

Unlocking the secrets to biological aging has perhaps been the ultimate scientific quest for many years.

Rapid cell deterioration.

Over time the activity of this genetic regulators seems to decline and cumulative cell damage can occur

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

So we've been trying in our lab now to develop drugs that will activate this FOXO cell using human cells now in order to try and come up with drugs that will delay aging and age related diseases.

Let's make it concrete.

I'm reading massive cellular deterioration.

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.

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

They control how the cells grow and differentiate.

It can actually make itself glow.

We're actually injecting contrast into the organ.

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

Maybe these cells eventually differentiate into things that'll turn to my brain.

And it's in men as well as in women.

disabling, reversing cell cycle inhibitors.

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

Fat derived stem cells are adult stem cells.

And this all changed in the late 19th century.

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.

But it differentiated.

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

And so guess what, scientists around the world and in the labs are racing to convert aging adult cells aging adult cells from you and me they are racing to reprogram these cells back into more useful IPS cells.

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

Cell division

Cell radius

They were developed in Japan pretty recently.

From Conception to Birth Oocyte

Fuel cells.

That's what your genes are doing every day.

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

And that's your ancestor.

SR So what do you think, Xu?

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

If some cells suddenly decide to start reading other instructions, they can actually change from one type to another.

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.
