Central nervous system consists of brain, cerebellum, medulla oblongata and spinal cord.

She had a spina bifida defect, a spinal cord abnormality.

It paralyzes you. It starts by killing the motor neurons in your spinal cord.

In 1879, she suffered spinal cord injuries in a fall from a stepladder.

They picked as much broken bone as they could that had lodged in my spinal cord.

The backbone of tomorrow s societies, after all, will be built not by robots or digital platforms, but by their citizens.

Heart disease, stroke, diabetes, spinal cord injury, muscular dystrophy, retinal eye diseases are any of these conditions relevant, personally, to you?

As we speak, the world's first human embryonic stem cell trial for spinal cord injury is currently underway following the USFDA approval.

Well the body works by starting a motor command in your brain, going down your spinal cord, out the nerves and to your periphery.

The headquarters for orgasm, along the spinal nerve, is something called the sacral nerve root, which is back here.

People with spinal cord injuries, like paraplegias, quadriplegias, will often develop a very, very sensitive area right above the level of their injury, wherever that is.

But then the doctor came over to me, and she said, Janine, the operation was a success, and we've picked as much bone out of your spinal cord as we could, but the damage is permanent.

Instead of it being the case that that junction box in the spinal cord is just simple where one nerve connects with the next nerve by releasing these little brown packets of chemical information called neurotransmitters in a linear one on one fashion, in fact, what happens is the neurotransmitters spill out in three dimensions laterally, vertically, up and down in the spinal cord and they start interacting with other adjacent cells.

These cells, called glial cells, were once thought to be unimportant structural elements of the spinal cord that did nothing more than hold all the important things together, like the nerves.

And you can see, they're ranging from shoes, rings that were made out of stainless steal, phone covers out of plastic, all the way through to spinal implants, for example, that were created out of medical grade titanium, and engine parts.

He is an American to the backbone.

He's head over heels in love.

I was lying on a thin, hard spinal bed.

He's rotten to the core.

I'll probably get hammered drunk.

So actually how do we harvest this bone marrow?

And the Marrow Miner, the way it works is shown here.

Daniel Kraft invents a better way to harvest bone marrow

Coir pith is used as manure in the vases.

Daniel Kraft demos his Marrow Miner a new device that quickly harvests life saving bone marrow with minimal pain to the donor. He emphasizes that the adult stem cells found in bone marrow can be used to treat many terminal conditions, from Parkinson's to heart disease.

Worldwide, more than 11 million people have put their names on donor registries for bone marrow, signifying their willingness to donate their marrow to a stranger.

It may encourage more people to sign up to be potential live saving bone marrow donors.

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.

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

We've just come out, we're commercializing, this year, generation 2.0 of the Marrow Miner.

Plant vases made of coir are the new export materials.

I invented a device called the MarrowMiner, a much less invasive way for harvesting bone marrow.

We're sending his marrow across the country to save the life of a child with leukemia.

And so this informs, among other things, of course, a treatment for bone marrow transplant, which he undertakes.

Plant vases made of coir fibre and coir piths are eco friendly and cheap.

After a bone marrow transplant, chemotherapy sessions, she's had to give up modeling.

So I thought of a minimally invasive approach, and a new device that we call the Marrow Miner.

So it enables you to very rapidly aspirate, or suck out, rich bone marrow very quickly through one hole.

And ultimately and here's a picture of our bone marrow transplant survivors, who come together for a reunion each year at Stanford.

It is a fact that when our organs or tissues are injured, our bone marrow releases stem cells into our circulation.

Mice with multiple myeloma, an incurable malignancy of the bone marrow, respond dramatically to the treatment with this drug.

This is the last act on this Earth of a little girl called Heidi, five years old, before she died of cancer to the spine.

I had packed only running shoes and leather boots, and both were soaked to the core after several days of downpours.

Now, inspired by Jill Bolte Taylor last year, I didn't bring a human brain, but I did bring a liter of bone marrow.

The genus name is derived from the Greek words en (within), kephali (head), and artos (bread), referring to the use of the pith to make food.
