What is your doctor doing to get this into human clinical trials?

A couple of paragraphs from here.
When the neural stem cells in our
brains get older, they create far fewer neurons. This plays a role in
neurodegenerative diseases from Alzheimer’s to Parkinson’s.
It also plays a role in our increasingly deficient ability to simply find those car keys.
New research is changing that paradigm. Among others, a team from
Japan’s Keio University, and the Riken national research institute,
reports this month in Proceedings of the National Academies of Science
they used embryonic mice to find a micro-RNA (ribonucleic acid)
molecule that controls neuron making at that young age. When they
applied knowledge they gain from that embryonic stage to older neural
stem cells (NSCs) that had stopped making neurons, those cells produced
neurons again. The mechanism is believed to exist in humans as well.
Senior Author Hideyuki Okano tells Bioscience Technology:
“We observed the neurogenic-to-gliogenic switching in developing NSCs.”
That is, Okano and his team examined embryonic NSCs for the proportion
of neurons they produced—versus supporting glial cells. They found, as
other have, that the developing embryo creates neurons first, then
switches over to making glial cells. The team isolated the
microRNA-17/106-p38 axis responsible for that initial switch in
embryonic development.
When they turned on and off this embryonic pathway in older, post-natal
NSCs in the Petri dish, they persuaded older post-natal NSCs to switch
from glial cell-producing to neuron-producing.
Use the labels in the right column to find what you want. Or you can go thru them one by one, there are only 29,112 posts. Searching is done in the search box in upper left corner. I blog on anything to do with stroke.DO NOT DO ANYTHING SUGGESTED HERE AS I AM NOT MEDICALLY TRAINED, YOUR DOCTOR IS, LISTEN TO THEM. BUT I BET THEY DON'T KNOW HOW TO GET YOU 100% RECOVERED. I DON'T EITHER, BUT HAVE PLENTY OF QUESTIONS FOR YOUR DOCTOR TO ANSWER.
Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.
What this blog is for:
My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.
