An astonishing degree'

A stem cell gel developed by scientists can regenerate broken spinal cord nerves, research has shown.The gel is applied to the site of an injury. In rats with completely severed spinal cords, it produced an 'astonishing degree' of nerve growth, U.S. scientists said.Treated animals which were previously paralysed experienced 'significant' functional improvement and were able to move all the joints of their affected legs.

The gel was made by embedding neural stem cells in a mixture of blood clotting protein and growth chemicals.Lead researcher Professor Mark Tuszynski, from the University of California at San Diego, said: 'Using this method, after six weeks the number of axons (nerve fibres) emerging from the injury site exceeded by 200-fold what had ever been seen before.

'The axons also grew ten times the length of axons in any previous study, and, importantly, the regeneration of these axons resulted in significant functional improvement.'

Similar results were obtained in the laboratory using human stem cells.Cells were tagged with a fluorescent protein so that their progress could be monitored.

Scientists watched them grow, become neurons, and sprout axons.In June, it was announced that researchers had successfully grown living bones in a laboratory using stem cells.

That technique could in future be used to replace shattered limbs, treat osteoporosis and arthritis and fix defects such as cleft palate, it was claimed.

The researchers took around a month to transform stem cells originally taken from fat tissue into sections of fully-formed bone up to several centimetres long.Standard bone grafts involve two procedures, to cut bone from elsewhere in the patient's body before transplanting it into the damaged area, which carry the risk of infection and complications.

Bone can also be obtained from donations, but this brings the chance of rejection.The new method would allow bones to be custom made to shape outside the body, using the patients own stem cells, removing the need for a potentially traumatic operation and reducing the likelihood of rejection.

So far the research has been carried out only on animals but a patient trial is planned for later this year.That Israeli technology, developed by biotech company Bonus BioGroup and researchers at the Technion Institute of Research, involves growing the bone to fit the exact shape and size of the damaged area.

I thought stem cell research is banned?.

Only in some countries. This is good news.

Only fetal stem cells from aborted babies, and only in some countries. But these are neural stems cells, meaning that they aren't coming from fetuses. But where are they coming from then?

I knew that :Nerd:

hopefully some day this will be applied and successful. It will be a remarkable achievement indeed.

bush banned it in the us because he was malinformed (idiot) but Obama overthrew that law and it is now legal. The issue is that many believe the only source of stem cells is from unborn fetus'....stem cells can also be harvested from adults, placenta, etc without harming the baby.....

We all have stem cells in our bodies, it is what helps us heal after an injury etc......

They are actually quite remarkable....they are basically "blanks" waiting for input to determine what kind of cell it will be. Put the right marker on it, and it could turn into a skin cell, a muscle cell, bone cell, and here they're using it to generate spinal cord nerves....
