So we set out by looking at how these molecules are put together.

And we then can re perfuse the liver with cells, preserving the blood vessel tree.

You place the muscle cells on the outside.

And what we do is we, to make a blood vessel, same strategy.

And in fact, every cell in our body has a little blood vessel that's near by.

And, there are other frequently dividing cells in your body

Because we'd rather take those cells which already know that those are the cell types you want.

End to end, that would form a line that would circle the earth twice.

So, all these guys over here, these are the true capillaries.

And once those vessels invade the cancer, it can expand, it can invade local tissues, and the same vessels that are feeding tumors allow cancer cells to exit into the circulation as metastases.

Then you start to take a look at adult life.

Nah, let's draw four, just for fun.

Part of the human immune system.

And you can think about any part of the body that you could be. Let's say a little toe cell. So let's say you're a toe cell and your job, of course, is to live and be happy,and you've got near by, a little blood vessel.

When it happens, you are significantly depleting the blood flow going downstream from there.

The walls are covered with villi where nutrient absorption takes place.

To rule out fetal blood cells.

And the first thing that makes me think is that blood vessels are like highways for the tumor cells.

And under the microscope, you can see hundreds of these brown stained blood vessels, capillaries that are feeding cancer cells, bringing oxygen and nutrients.

So, even though there's a blood vessel near by, really, no flow is happening, so I'll just write no flow .

You can hold it like a liver, but it has no cells it's just a skeleton of the liver.

In fact, if you actually block angiogenesis and prevent blood vessels from ever reaching cancer cells, tumors simply can't grow up.

What could we be adding to our diet that's naturally antiangiogenic, and that could boost the body's defense system, and beat back those blood vessels that are feeding cancers?

It was a rare gem a brain tumor, hemangioblastoma the gift that keeps on giving.

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.

Or we can build endoscopes that can see deep inside the body around occluders, and also for cardioscopes.

We worked with a theme, which is, you've got macrophages that are streaming down a capillary, and they're touching the surface of the capillary wall, and they're picking up information from cells that are on the capillary wall, and they are given this information that there's an inflammation somewhere outside, where they can't see and sense.

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

So where is the blood gonna go?

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

So, a Spanish woman who was dying of T.B. had a donor trachea, they took all the cells off the trachea, they spraypainted her stem cells onto that cartilage.

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.

They're proteins that are controlling things like ion channel movement.

The smallest blood vessels are called capillaries.

Let me actually just gonna call them that.

And all that systemic means is that I'm refering to the entire body.

I checked myself into a hospital and they told me I had hepatitis C.

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

Fat derived stem cells are adult stem cells.

Well if the main job is to serve the needs of cells, then the coronary vessels fall under the systmic flow.

He had many capillaries burst in his legs.

We've got 19 billion of them in our bodies.

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

I mean remember, the heart is made up of thousands and thousands, actually tens of thousands of cells and those cells, just like our toe cell that we drew, they also need oxygen, nutrients, and have waste.
