But she also found osteocytes, which are the cells that laid down the bones.

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

So, is it possible that the tumor cells are going to the skeletal muscle tissue, but once in contact inside the skeletal muscle tissue, MyoD acts upon these tumor cells and causes them to become skeletal muscle cells?

Adult stem cells are throughout our body, including the blood forming stem cells in our bone marrow, which we've been using as a form of stem cell therapy for over 40 years.

And what MyoD essentially does is, it causes cells to differentiate into muscle cells. 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.

We use those in my field of bone marrow transplantation.

These cancers include acute lymphoblastic leukaemia acute myelogenous leukaemia chronic lymphocytic leukaemia hairy cell leukaemia non Hodgkin's lymphoma Hodgkin's disease melodysplastic syndrome multiple myeloma retinoblastoma Ewing sarcoma Wilms tumour neuroblastoma sarcoma rhabdomyosarcoma testis tumour and lung cancer.

We take our own bone marrow cells and treat a patient with a heart attack, we can see much improved heart function and actually better survival using our own bone marrow drive cells after a heart attack.

And in the measure that we learn how chickens grow wings, and what the program is for those cells to differentiate, one of the things we're going to be able to do is to stop undifferentiated cells, which you know as cancer, and one of the things we're going to learn how to do is how to reprogram cells like stem cells in such a way that they express bone, stomach, skin, pancreas.

Last year, this group was able to take all the cells off a heart, leaving just the cartilage.

These are diatoms, single celled phytoplankton with skeletons of silicon ...

So why should you care? Bone marrow is a very rich source of adult stem cells.

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.

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

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.

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.

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.

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

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.

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.

And we found, to our surprise, that we not only got bone marrow out, but we got 10 times the stem cell activity in the marrow from the Marrow Miner, compared to the normal device.

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.

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

So I've studied a lot about stem cells embryonic stem cells are particularly powerful.

And in our lab, we are focused on taking fat and reprogramming mounds of fat into fountains of youthful cells cells that we may use to then form other, more specialized, cells, which one day may be used as cell transplants.

And they will either enter into this so called cellular suicide, programmed cell death, or they will form unhealthy daughter cells and enter into apoptosis once they have divided.

Watch when these two large protocells, the hybrid ones, fuse together.

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.
