Get the paddles.

I've got the paddles.

Oh,it's a defibrillator.

unfortunately, i don't have a defibrillator!

Asystole. Charge the paddles. We'll start at 200.

I just,I gave her a price and that's it. Nothing happened.

And these micro machines power how a cell moves.

Um,I sold the defibrillator,and you were amazingly helpful. Oh,good.

But, I mean it gets more interesting.

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.

That's their job.

Օրինակ իմ լյարդը ենթամիավոր է Սալ ի և դա օրգան է, օրգանոիդը բջջի ենթամիավոր է

I don't know.

Feel her heart beat.

But,um,the defibrillator,it's used. So you'll probably get 400 or 500 bucks for it.

Your rhythm becomes irregular, and that's what happened 45 minutes later.

You could now start doing surgery everywhere, on the gut, on the liver, on the heart, on the brain.

It has everything an ambulance has except for a bed.

Well, heart cells are pretty greedy.

I said some of them will turn into brain cells.

What you die of is increasing organ failure, with your respiratory, cardiac, renal, whatever organs packing up.

You could, if you want, compare this to, on the one hand, a myocardial infarction, a heart attack, where you have dead tissue in the heart, versus an arrhythmia, where the organ simply isn't functioning because of the communication problems within it.

What else do we know about the heart?

Cells form tissues, tissues form organs, organs form us.

This is actually a heart valve that we've engineered, and you can see here, we have the structure of the heart valve and we've seeded that with cells, and then we exercise it.

I'm going to show you just how early this technology is.

Each one has his story.

We don't need to teach it to become another cell type.

Therefore, 99 percent of people are organ donors.

Your heart rate is jacked.

In the United States, there are 60,000 people who have a pacemaker that connects to the Internet.

On the left, we see a tiny piece of beating heart tissue that I engineered from rat cells in the lab.

Well, if you don't know whether if you're studying XX or XY cells

We exercise these prior to implantation.

And it's collected by my general practitioner as well, so he can see what's my problem in weight, not on the very moment that I need cardiologic support or something like it, but also looking backward.

So that all the cells of your body the skin cells, the cells of your liver, and of your heart, and even of your ear, those cells know, at a fundamental molecular level, whether they are XX or XY.

My heart quickened.

The doctor here removed that thing from his chest.

They have on the other end of those tethers a little muscle. This makes perfect sense if you think about it.

Then, they sprayed stem cells onto that heart, from a mouse.

You already saw the work by Tony Atala on TED, but this ability to start filling things like inkjet cartridges with cells are allowing us to print skin, organs and a whole series of other body parts.

When you exercise your heart beats faster.

And he's sitting there in front of the Haptic device, the force feedback system, and he's moving his pen towards the heart, and the heart is now beating in front of him, so he can see how the heart is beating.

And that's exactly what we did here.

The heart works slowly.
