less than half the size of a postage stamp.

All you need is a single oncogene.

Not only that, but they can also be used for disease models.

Let's see how powerful just one of these essentials can be.

That little issue took the team two years to solve.

In the lab, we micro pattern channels in the biomaterials on which we grow the cells, and this allows us to flow the cell culture media, the cells' food, through the scaffolds where we're growing the cells a lot like what you might expect from a capillary bed in the heart.

looked at it under the microscope, you plated the culture, you injected the antiserum.

Bacteria are just tiny cells, harmless.

We induce cells, okay, say, skin cells, by adding a few genes to them, culturing them, and then harvesting them.

The tissue growing technology here is...

And what we do is we grow extracellular matrix from pigs.

In order to do that, however, we needed to have a method of distinguishing normal from malignant, and on the left is the single normal cell, human breast, put in three dimensional gooey gel that has extracellular matrix, it makes all these beautiful structures.

We grow the cells outside the body in large quantities.

And we know staph can do amazing things.

fungal.

What we did is, we took tissue culture cells and infected them with adenovirus, and you can see this little yellow barcode next to adenovirus.

These are spores this is in their spores.

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.

The first thing you do as a scientist is, you make sure stuff works.

The tissue could be grown in Copenhagen and implanted here.

Hyalograft C. We grow tissue from your own cells.

And in fact, the smallest unit of matter that can evolve independently is, in fact, a single cell a bacteria.

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

Bugs.

Եկեք դա նշեմ բջջային թաղանթ

And it could be any type of cell.

At the Lurie Family Center for Animal Imaging, our colleague, Andrew Kung, grew this cancer successfully in mice without ever touching plastic.

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

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

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.

Well, the heart beats, rhythmically, tirelessly, faithfully.

And when I made the videos on bacteria I said, hey for every one human cell we have twenty bacteria cells.

We wanted to get something like a fossil record of the building, and to do this, we sampled dust.

Bruce Lipton PhD Cell Biologist that it really changed the whole course of my education and my life.

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.

We plate them into dishes that we sometimes call petri dishes.

Fat derived stem cells are adult stem cells.

We think bacteria made the rules for how multicellular organization works.

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

This is the whole cell.

If, for example, you used a cell culture that's chronically infected with papilloma, you get a little computer readout here, and our algorithm says it's probably papilloma type 18.

I shouldn't say cell wall.

They get pulled apart even more.

So if you look right there, it finds that little bacterium, and it engulfs it and eats it.
