The pancreas turns over cells every 24 hours,

There's this experimental treatment for Jack's disease, but he needs compatible stem cells.

You see the cells coming back out.

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.

As the world population ages, scientists are racing to discover new ways to enhance the power of the body to heal itself through stem cells.

That's a way to do it.

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

Radiation hits whatever you point it at, and your blood stream carries chemo therapeutics all over your body.

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

Skin flakes off, hairs grow, nails, that kind of stuff but every cell in your body is replaced at some point.

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

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

Fat derived stem cells are adult stem cells.

Indeed, there is a lot of hype, but also hope that the promise of stem cells will one day provide cures for a whole range of conditions.

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

You place the muscle cells on the outside.

It's now being seeded with cartilage.

We didn't have disease modeling with human cells, so we'd been testing them on cells of mice or other creatures or cells that we engineer, but they don't have the characteristics of the diseases that we're actually trying to cure.

Cell division

Cell radius

They were developed in Japan pretty recently.

From Conception to Birth Oocyte

Fuel cells.

Radiation and most forms of chemo work by physically shredding the cells' DNA or disrupting the copying machinery.

In these cells, the mission is to move blood around their body.

And that's your ancestor.

There are two ways

This, however, is taking the approach of restoring cells to their original nature, reminding them of what they're supposed to do.

So if I start off with a diploid cell, and that's my diploid cell right there, this would be a germ cell.

I thought to myself, why not take the individual cells out of the pancreas the cells that secrete insulin to cure diabetes and transplant these cells? technically a much simpler procedure than having to grapple with the complexities of transplanting a whole organ.

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

So this is my body cells.

This is the whole cell.

I believe matter begets life

They get pulled apart even more.

Max cells

I shouldn't say cell wall.

celermitosis.

Եվ ես ասացի, որ սա հիմնականում բաժանումն է, քանի որ երբ որոշ մարդիկ նայում են որոշ բջիջներին և տեսնում են կորիզ և մեկ այլ բջիջներ ու չեն տեսնում կորիզը, նրանք ասում են, թե սա լավ միջոց է դասակարգելու օրգանիզմները

That turns out to be a big deal because now you can take, not just mouse cells, but you can human skin cells and turn them into human stem cells.

And then what they did in October is they took skin cells, turned them into stem cells and began to turn them into liver cells.

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.
