In case you’ve missed this — stem cells have been used to partially restore movement in a 38 year old man who had his spinal cord completely severed by a knife attack in 2010. The cells came from his nose, and are technically olfactory ensheathing cells (OEC). They are unique cells — the only nerve fibres we know of that grow and make connections with the central nervous system. It’s no magic instant bullet, but a first step. It’s taken 19 months of intensive rehab after the transplant, but he is now able to drive. It’s not known if this procedure can help with paralysis caused by other, more messy causes of spinal breaks. The stab wound was a very clean cut.
It is almost 30 years since Prof. Geoffrey Raisman first identified the potential of OEC’s to repair nerve damage in mice. In November 2012 researchers in Edinburgh were able to restore a dogs ability to move hind legs.
Speaking earlier today Geoffrey Raisman described the results as “more impressive than man walking on the moon”. — speakingofresearch
There are at least three different methods of possibly curing paralysis which have all made announcements this year. In May […]
There’s a fascinating study out this week suggesting that if we fast for three or four days a couple of times a year we can regenerate white blood stem cells. Fasting cuts down the number of white blood cells during the fast, but afterwards they recover, and then some.
This new result comes from both mice and phase I clinical human trials. Probably in paleolithic times, famine or at least hungry days were a part of nearly everyone’s life. Many different philosophies and religions have fasting traditions. Apparently our genes are selected to deal with that, and being short of food makes the immune system do a kind of efficiency sweep. Perhaps access to unnaturally continuous food stops our stem cells from reactivating? Something to think about from Killjoy Jo. 😉 Yes, fasting is not exactly fun, but nor is cancer. For what it’s worth, the hard part of a fast is usually the start.
Obviously, consult your doc, do your own research, etc.

Fasting for three days can regenerate the entire immune system, even in the elderly, scientists have found in a breakthrough described as remarkable.

Australia could be leading the world in research that will save lives and earn money. Instead we lead the world in gullible obedience to an absurd scheme to change the weather.
Making human body parts from off-the-shelf or customized cells is a vast improvement on waiting for healthy people to die and donate, and a lifetime of immunosuppressants. Any delay in developing these techniques will surely cost lives and prolong disability. Those who do develop and patent these techniques are bound to profit and be able to afford even more research, and will improve national productivity as well as the quality of life. For those on waiting lists, spending $3billion on solar panels to stop storms and hold back the sea is the cruelest waste.
This type of medical work could make waiting lists for organ-donation a thing of the past. The political vanity of supporting useless causes for the sake of symbolism has a ghastly price.

This week in stem cell news one research group announced they’d accidentally figured out a way to easily convert human bone-marrow stem cells into brain cells which could in future repair spinal or brain damage. Another group showed that if you happen to be a particular type of old mouse with memory problems, researchers can give you a transplant of stem cells that restore your learning and memoryand help you swim through water mazes faster. But seriously, these discoveries could help a lot of very needy people.
Meanwhile Australia, celebrated it’s one millionth roofing panel that provide expensive, irregular electricity.
Ladies and Gentlemen — there is a revolution going on, and it’s not the Green one. How much could $2 billion wasted dollars have achieved if it were spent wisely?
These two studies fit together quite well — the first shows it’s possible to use stem cells to restore brain function, the second suggests it might be easier to get the right stem cells than anyone thought.
