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.

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

They control how the cells grow and differentiate.

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.

Let's make it concrete.

I'm reading massive cellular deterioration.

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

It can actually make itself glow.

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

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

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

We're actually injecting contrast into the organ.

And this all changed in the late 19th century.

That's what your genes are doing every day.

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.

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

But it differentiated.

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.

disabling, reversing cell cycle inhibitors.

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

This is the whole cell.

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

I shouldn't say cell wall.

SR So what do you think, Xu?

lifestyle factors, nutritional factors Tha all effect how we age. but now much as known about these cellular processes that incorporates these various factors, and lead to people aging slowly or more quickly

Fat derived stem cells are adult stem cells.

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

So this is my body cells.

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

When you take a chemotherapeutic drug, it will hit all of these cells.

And, there are other frequently dividing cells in your body

It remembers that it's cancer.

It is a simple chemical model of a living cell, and if you consider for example a cell in your body may have on the order of millions of different types of molecules that need to come together, play together in a complex network to produce something that we call alive.

Cell division
