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.

Boosting muscle stem cells to treat muscular dystrophy and aging muscles

Would this help stroke survivors due to the likely atrophy occurring? Or are these other possibilities better? Does your doctor have anything for muscle atrophy? Does she even know that survivors need something to prevent atrophy since they have nothing that will get you 100% recovered?

Boosting muscle stem cells to treat muscular dystrophy and aging muscles

Newswise | April 17, 2019
Lying within our muscles are stem cells, invisible engines that drive the tissue’s growth and repair. Understanding the signal(s) that direct muscle stem cells to spring into action could uncover new ways to promote muscle growth. However, these mechanisms are poorly understood.

Now, scientists from Sanford Burnham Prebys have uncovered a molecular signaling pathway involving Stat3 and Fam3a proteins that regulates how muscle stem cells decide whether to self-renew or differentiate—an insight that could lead to muscle-boosting therapeutics for muscular dystrophies or age-related muscle decline. The study was published in Nature Communications.
“Muscle stem cells can ‘burn out’ trying to regenerate tissue during the natural aging process or due to chronic muscle disease,” says Alessandra Sacco, PhD, senior author of the paper and associate professor in the Development, Aging, and Regeneration Program at Sanford Burnham Prebys. “We believe we have found promising drug targets that direct muscle stem cells to ‘make the right decision’ and stimulate muscle repair, potentially helping muscle tissue regeneration and maintaining tissue function in chronic conditions such as muscular dystrophy and aging.”
Muscle wasting occurs as part of the natural aging process, called sarcopenia, or due to genetic diseases such as muscular dystrophy. Sarcopenia affects nearly 10% of adults over the age of 50 and nearly half of individuals in their 80s. The condition leads to loss of independence and contributes to falls, a leading cause of accidental death in people age 65 or older. Muscular dystrophies are a group of more than 30 genetic diseases characterized by progressive muscle weakness and degeneration. A cure does not exist.
Muscle stem cells select between two fates over a person’s lifetime: Either differentiate to become adult muscle cells or self-renew to replenish the stem cell population. Accumulating evidence shows that mitochondrial respiration (cellular breathing) is a key switch that drives muscle stem cells to differentiate, an energy-intensive process, instead of self-renew.
In the study, the scientists used mouse models to demonstrate that Stat3 promotes mitochondrial respiration. Because Stat3 regulates many cellular processes, the scientists combed through genes expressed during muscle growth to find additional proteins regulated by Stat3 that might serve as more specific targets.
These efforts uncovered the protein Fam3a. Further work conducted, including generating a mouse model and cell lines that lack Fam3a, demonstrated that the protein is required for muscle stem cell differentiation and muscle growth. The researchers also showed that Fam3a is secreted by muscle cells during muscle repair, and treatment with the protein restored mitochondrial respiration and stem cell differentiation in muscle stem cells that lacked Stat3—all demonstrating the integral role of Fam3a in determining muscle stem cells’ fate.
“As the number of people over the age of 65 rises due to the aging of the baby boomer generation, it is important to not only extend life span but also health span—the years we can remain healthy and active,” says David Sala, PhD, the first author of the paper and a postdoctoral researcher in the Sacco laboratory. “The ability to boost and maintain muscle tissue function can help more people live an active and independent life. The results of our research can also find applications for muscle-wasting disorders such as muscular dystrophy.”
The scientists are already conducting preclinical studies to validate Fam3a as a therapeutic target. They also hope their findings could apply to stem cells that differentiate to create other tissues, which could help treat other degenerative tissue diseases.
