From the chest down no less. This is amazing, and it just goes to show, the nose knows

For the work blocked…

A paralysed man has been able to walk again after a pioneering therapy that involved transplanting cells from his nasal cavity into his spinal cord. Darek Fidyka, who was paralysed from the chest down in a knife attack in 2010, can now walk using a frame.

The treatment, a world first, was carried out by surgeons in Poland in collaboration with scientists in London. I have waited 40 years for something like this”

BBC One's Panorama programme had unique access to the project and spent a year charting the patient's rehabilitation.

Darek Fidyka, 40, was paralysed after being stabbed repeatedly in the back in the 2010 attack. He said walking again - with the support of a frame - was "an incredible feeling", adding: "When you can't feel almost half your body, you are helpless, but when it starts coming back it's like you were born again." Prof Geoff Raisman, chair of neural regeneration at University College London's Institute of Neurology, led the UK research team. He said what had been achieved was "more impressive than man walking on the moon".

The treatment used olfactory ensheathing cells (OECs) - specialist cells that form part of the sense of smell. OECs act as pathway cells that enable nerve fibres in the olfactory system to be continually renewed.
In the first of two operations, surgeons removed one of the patient's olfactory bulbs and grew the cells in culture. Two weeks later they transplanted the OECs into the spinal cord, which had been cut through in the knife attack apart from a thin strip of scar tissue on the right. They had just a drop of material to work with - about 500,000 cells.

About 100 micro-injections of OECs were made above and below the injury. Four thin strips of nerve tissue were taken from the patient's ankle and placed across an 8mm (0.3in) gap on the left side of the cord.
The scientists believe the OECs provided a pathway to enable fibres above and below the injury to reconnect, using the nerve grafts to bridge the gap in the cord.

1) One of the patient's two olfactory bulbs was removed and the olfactory ensheathing cells (OECs) were grown in culture

2) 100 micro injections of OECs were made above and below the damaged area of the spinal cord

3) Four strips of nerve tissue were placed across an 8mm gap in the spinal cord. The scientists believe the OECs acted as a pathway to stimulate the spinal cord cells to regenerate, using the nerve grafts as a bridge to cross the severed cord.

Before the treatment, Mr Fidyka had been paralysed for nearly two years and had shown no sign of recovery despite many months of intensive physiotherapy. This programme of exercise - five hours per day, five days a week - has continued after the transplant at the Akson Neuro-Rehabilitation Center in Wroclaw. Mr Fidyka first noticed that the treatment had been successful after about three months, when his left thigh began putting on muscle.
Six months after surgery, Mr Fidyka was able to take his first tentative steps along parallel bars, using leg braces and the support of a physiotherapist. Two years after the treatment, he can now walk outside the rehabilitation centre using a frame.

He has also recovered some bladder and bowel sensation and sexual function. Dr Pawel Tabakow, consultant neurosurgeon at Wroclaw University Hospital, who led the Polish research team, said: "It's amazing to see how regeneration of the spinal cord, something that was thought impossible for many years, is becoming a reality."
Mr Fidyka still tires quickly when walking, but said: "I think it's realistic that one day I will become independent.

"What I have learned is that you must never give up but keep fighting, because some door will open in life."

The groundbreaking research was supported by the Nicholls Spinal Injury Foundation (NSIF) and the UK Stem Cell Foundation. NSIF was set up by chef David Nicholls after his son Daniel was paralysed from the arms down in a swimming accident in 2003. To date the charity has given £1m to fund the research in London and a further £240,000 for the work in Poland.

The breakthrough
A key difference with Mr Fidyka was that the scientists were able use the patient's olfactory bulb, which is the richest source of olfactory ensheathing cells. This meant there was no danger of rejection, so no need for immunosuppressive drugs used in conventional transplants. Most of the repair of Mr Fidyka's spinal cord was done on the left side, where there was an 8mm gap.

He has since regained muscle mass and movement mostly on that side. Scientists believe this is evidence that the recovery is due to regeneration, as signals from the brain controlling muscles in the left leg travel down the left side of the spinal cord. MRI scans suggest that the gap in the cord has closed up following the treatment.

None of those involved in the research want to profit from it. Prof Geoff Raisman said: "It would be my proudest boast if I could say that no patient had had to pay one penny for any of the information we have found."
NSIF said if there were any patents arising, it would acquire them so as to make the technique freely available.

The complex neural circuitry responsible for our sense of smell is the only part of the nervous system that regenerates throughout adult life. It is this ability that scientists have tried to exploit in stimulating repair in the spinal cord.
Every time we breathe, molecules carrying different odours in the air come into contact with nerve cells in the nose. These transmit messages to our olfactory bulbs - at the very top of the nasal cavity, sitting at the base of the brain.

The nerve cells are being continually damaged and must be replaced. This process of regeneration is made possible by olfactory ensheathing cells (OECs), which provide a pathway for the fibres to grow back.
Mr Nicholls said: "When Dan had his accident I made him a promise that, one day, he would walk again. I set up the charity to raise funds purely for research into repairing the spinal cord. The results with Darek show we are making significant progress towards that goal."

Prof Wagih El Masri said: "Although the clinical neurological recovery is to date modest, this intervention has resulted in findings of compelling scientific significance." The consultant spinal injuries surgeon, who has treated thousands of patients in the UK, added: "I have waited 40 years for something like this."
All those involved in the research are keen not to raise false hopes in patients and stress that the success will need to be repeated to show definitively whether it can stimulate spinal cord regeneration.
The scientists hope to treat another 10 patients, in Poland and Britain over the coming years, although that will depend on the research receiving funding. Dr Tabakow said: "Our team in Poland would be prepared to consider patients from anywhere in the world who are suitable for this therapy. They are likely to have had a knife wound injury where the spinal cord has been cleanly severed.

Sir Richard Sykes, chair of the UK Stem Cell Foundation, said: "The first patient is an inspirational and important step, which brings years of laboratory research towards the clinical testbed."
"To fully develop future treatments that benefit the 3 million paralysed globally will need continued investment for wide scale clinical trials,"

Prof Raisman has spent more than 40 years studying how to repair the spinal cord. In animal studies he showed that OECs injected into the rat spinal cord could reverse paralysis.
In 2005, Prof Raisman was approached by a Polish neurosurgeon who had begun researching how to apply the technique in humans.

Dr Tabakow carried out an initial trial involving three paralysed patients who each had a small amount of OECs injected in their damaged spinal cords.
While none showed any significant improvement, the main purpose of the study was achieved, showing that the treatment was safe.

That is pretty amazing.

**Da Boss**

Wow! That is some seriously clever work.

**Aesop the God Awful**

That is very impressive, but...

Who are we to play God?

We are the music makers. We are the dreamers of dreams.

The gods only help those who help themselves.

This man is pretty damn awesome and I hope we eventually can see more of these kinds of stories.... Maybe there's hope for Hawking yet

**Crazy_Carnifex**

I sincerely hope that this technique truly does work, continues to be successful, and is improved over the coming years.

**hotsauceman1**

But now heven has to smell his spinal cord all day

**nkelsch**

If I had to look like Voldemort and have no nose to walk, I totally would too!

Yay Science!

**Sigvatr**

South Park did it.

If we have the power to keep someone from suffering, then we should use it.

Why?

**streamdragon**

Er... because suffering is bad?

**Co'tor Shas**

If any god would damn this, than that is truly no god worth worshiping.

**Desubot**

Oh i heard of this a while back.

cool to see that it seems to work.

Cant wait for regrowing limbs with magic pig powder.

**LuciusAR**

I don't see how fixing disabilities in this way is 'playing god'. Besides which 'playing god' is something of a meaningless cliche anyway. In what sense is curing paralysis playing at god whereas curing say cancer wouldn't be?

**Aesop the God Awful**

Don't let italics indicate sarcasm, gentlemen.

Marcus Aurelius... Nice

I do wonder, if we're using nose hair to "cure" paralysis, are we ever going to figure out what the appendix is for? Can we cure something with it? Even if it's something mundane and stupid, like male pattern baldness.

So when are you heading to Africa to build a few wells?

To get to my point directly: most people are immediately thinking that anything should be done to stop any suffering...not knowing why.

So that's where I got it from.

I have this thing where I remember quotes and ideas without knowing I remember them, and then quote them think that I came up with them. Then 5 seconds later I realize, wait, I've heard that before...

My mind is weird.

**TheMeanDM**

Isn't that more along the lines of Epicurus?

**Ensis Ferrae**

This is what I'm talking about.... but google images shows a couple of these where the quote itself was misattributed to Aurelius (I have not the time nor inclination to research this dispute at this time

)
