And the other really interesting thing is that when skeletal muscle there's been several reports that when skeletal muscle is injured, that's what correlates with metastases going to skeletal muscle.

So I decided to ask why.

It needs to be constantly contracting, so therefore it's almost selfish. It's grabbing its blood vessels for itself.

Skeletons...

Two elements that worked for me here are the first is 90 percent, I learned, of head and neck pain is through muscular skeletal imbalance.

So, there's so much interplay here.

MyoD acts upon these tumor cells and causes them to become skeletal muscle cells?

Endoskeletons.

The fetus' continual movement in the womb is necessary for muscular and skeletal growth.

So angiogenesis is really a central process to the pathogenesis of cancer.

Some of my hypotheses are that when you first think about skeletal muscle, there's a lot of blood vessels going to skeletal muscle.

So, is it possible that the tumor cells are going to the skeletal muscle tissue, but once in contact inside the skeletal muscle tissue,

And skeletal muscle constitutes 50 percent of our body, or over 50 percent of our body.

But once it starts moving throughout the body, that's when it becomes deadly.

The lumbar spine, the sacroiliac joint, the sacrum, the gluteus maximus muscle, the piriformis muscle, the sciatic notch, the ischial tuberosity, and the adductor tubercle of the proximal femur.

We don't see the origin of species.

There's an outer layer and an inner layer.

You can also see... my skeleton, (Laughter)

50 kilos for the entire fuselage.

Those are its targets.

I should clarify that.

Well, not the one we tagged!

All of those muscles work in a pattern along the back side of the body, the back half of the body.

But it struck me that I'd never heard of cancer of the heart, or cancer of any skeletal muscle for that matter.

We found this last year.

(English captions by Andrea Matsumoto from the University of Michigan)

It's strange, but it's like deeper it's muscle, vein, nerve, bone.

I notice they react completely differently.

They use a skeleton that we call a hydrostatic skeleton.

It's a little distorted, but I don't think it's the computer.

Also in the seated position, palpate anatomic landmarks for tenderness.

We needed the subtleties of the skin.

Two 600 models had a titanium alloy endoskeleton.

Maybe tumor cells are being disguised as skeletal muscle cells, and this is why it seems as if it is so rare.

These are being layered, one layer at a time, first the bone, we fill in the gaps with cartilage.

250 skeletons so far.

Still working my way around endoskeleton.

You're supposed to burn the endos.

Damn it, Cameron, you're supposed to burn the endos.

I've talked about a few of them. We really need to take that further.

So this compound, MyoD, has been tested on a lot of different cell types and been shown to actually convert this variety of cell types into skeletal muscle cells.

If I push a little bit harder, I'll go through the skin, and I can feel the bone structure inside.
