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.

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 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.

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.

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.

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

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.

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.

We're made of cells and stuff between cells.

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 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.

These are support cells astrocytes glia.

We then grow the cells outside the body, take the scaffold, coat the scaffold with the cells the patient's own cells, two different cell types.

To support valuable research efforts, Singapore has been putting in place a proper legal and ethical framework for stem cell research.

And in fact, this molecule prevents this adipocyte, this fat stem cell, from remembering how to make fat such that mice on a high fat diet, like the folks in my hometown of Chicago, fail to develop fatty liver, which is a major medical problem.

Or we can use cells alone, either your very own cells or different stem cell populations.

And the other part is on the inside where it sends signals into the cell.

A windpipe cell already knows it's a windpipe cell.

They discovered that adult cells, taken from you and me, could be reprogrammed back into embryonic like cells, which they termed IPS cells, or induced pluripotent stem cells.

In order to preserve the human species, it would be preferable surely to use gene therapy with caution, restricting it to somatic cells (body cells excluding germ cells), to the exclusion of germ cells (i.e. the cells used for sexual reproduction).

We thought that maybe nitric oxide affected cell death, and how cells survive, and their resistance to other things.

The immune cells developed into the tolerance promoting cells.

So you may not only have car cells, you may have Aston Martin cells.

And place cells also get this kind of path integration input from a kind of cell called a grid cell.

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.

So, 10 times more bacterial cells than human cells on a human being.
