Stem cells may be used as building blocks to repair damaged scaffolds within our body, or to provide new liver cells to repair damaged liver.

It's got a lot of cells in it too, right?

We perfuse the outside of the liver with the patient's own liver cells.

Liver cells, nerve cells, pancreatic cells we still can't grow them even today.

My body's an accumulation of ideas too the idea of skin cells, the idea of brain cells, the idea of liver cells.

It was in her brain, in her lungs, in her liver.

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.

If somehow we can cause these cells to differentiate to become bone tissue, lung tissue, liver tissue, whatever that cancer has been put there to do it would be a repair process. We'd end up better than we were before cancer.

So we hypothesized that female stem cells might be better at identifying the injury, doing some cellular repair or even producing new organs, which is one of the things that we're trying to do with stem cell therapy.

It's just a bunch of cells. You understand your liver.

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

Whereas a skin cell or a liver cell, for instance, can reproduce only more skin or liver, stem cells, which are the most robust at the beginning of human development, are master cells. As a fertilized egg turns into an embryo, and then a fetus, those initial stem cells somehow show their daughter cells how to become skin, liver, eye, or bone.

Cells that are capable of triggering inflammation are balanced by cells that promote tolerance, protecting the body without damaging sensitive tissues.

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

Two weeks later, we basically can lift this organ up, it feels like a liver, we can hold it like a liver, it looks like a liver, but it has no cells.

So we actually perfuse first the blood vessel tree with the patient's own blood vessel cells, and we then infiltrate the parenchyma with the liver cells.

The sudden loss of many brain cells as a result of strokes or injuries must have serious effects on an animal s survival. It seems likely that the replacement of neurons in the adult brain did not evolve to make up losses due to illness or lesion, but as a process of constant renewal, a few cells being replaced every day.

That's going to spray cells over that area.

We're removing the cancer cells, but we're revealing the previous damage that the body has tried to fix.

We actually take the donor liver, we use very mild detergents, and we, by using these mild detergents, we take all the cells out of the liver.

Each cell in the body contains DNA, which is responsible for producing the proteins that are necessary for a cell s functioning. Though all cells in the body have the same DNA, only a subset of the genes encoded by the DNA is expressed in each cell type, thus accounting for the difference between, say, a skin cell, a liver cell, and a brain cell.

The IML 2 studies of radiation biology showed damage to living cells as an effect of the natural space environment.

Now you can see it start. We're injecting the contrast into the organ into this decellularized liver.

A stem cell changes its identity through a process of triggering a signal literally turns on the liver cell gene inside the stem version. When scientists figure out how to flip these switches, it might be possible to introduce stem cells into the body and activate them so that they correctly replace damaged tissue, whatever it is.

In many forms of blindness, like retinitis pigmentosa, or macular degeneration, the photoreceptor cells have atrophied or been destroyed.

And today we can obtain cells from most every organ in your body, except for several which we still need stem cells for, like heart, liver, nerve and pancreas.

Cell loss, mutations in chromosomes, mutations in the mitochondria and so on.

So, I added these protocells together to the system, and protocell A and protocell B fused together to form a hybrid protocell AB.

For this fish, it's actually whole cells with nuclei and membranes.

As we speak, there are 117 or so clinical trials researching the use of stem cells for liver diseases.

This is a normal cell. This is a cancer cell.

So we can take these liver structures, which are not going to be used, and we then put them in a washing machine like structure that will allow the cells to be washed away.

We then take the cells, the vascular cells, blood vessel cells, we perfuse the vascular tree with the patient's own cells.

There's a class of cells, a fairly small cell, an inhibitory cell, that quiets its neighbors.

Stem cells may be used to deliver growth factors to repair damaged heart muscle or be differentiated into heart muscle cells to restore heart function.

Further understanding of the mechanisms of cellular damage caused by and of cellular responses to ionizing radiation and the biological effects in organisms will provide a sounder basis for determining the risks of radiation exposure.

We're made of cells and stuff between cells.

Good for our livers. Good for our immortal souls.

If you drink, you damage your liver, and then liver cancer occurs.

In effect, the cancer cell was forgetting it was cancer and becoming a normal cell.

Fat derived stem cells are adult stem cells.

Cells?

And if you had an injured organ, if you had a heart attack and we wanted to repair that injured area, do you want those robust, plentiful stem cells on the top?

And out in the cytoplasmic soup we have special proteins that are required for cell division that float freely in this soup in three dimensions.

But adult stem cells are not embryonic stem cells.
