Earlier this year, a group of scientists led by Yoo-Hun Suh at the Seoul National University Medical College published their work demonstrating the potential use of human adipose-derived stem cells (hASC‘s) in Parkinson’s therapy. Their article, Therapeutic potentials of human adipose-derived stem cells on the mouse model of Parkinson’s disease, was published in the academic journal Neurobiology of Aging.
Many Parkinson’s disease treatments aim to compensate for the loss of dopamine that is seen in the brains of Parkinson’s patients, but because those treatments have their limitations, focus has shifted to the use of stem cells as a therapeutic option for Parkinson’s disease. The rise in stem cell research for Parkinson’s disease has also increased as scientists have recognized the importance of mitochondrial deterioration in the development of Parkinson’s disease.
Stem cells that can be easily transplanted and readily proliferate are seen as ideal stem cell candidates for such treatments. hASC are pluripotent, meaning they can differentiate into a number of different types of cells, including cells that resemble neurons, the cells of the brain. These particular stem cells are useful because they tend not to create a reaction by the immune system, and they can pass the blood-brain barrier and proliferate within the brain.
In this study, the researchers used a common mouse model of Parkinson’s disease, which is created with a specific neurotoxin called 6-hydroxydopamine (6-OHDA). They injected hASC into the veins of mice and assessed how these stem cells affected Parkinson’s disease symptoms, dopamine levels in the striatum, the part of the brain affected by Parkinson’s disease, and the integrity of mitochondria.
The researchers found that hASC improved the motor deficits in the mice modeled to display Parkinson’s disease symptoms. Using positron emission tomography (PET) imaging, the researchers also showed increased dopamine levels in the striatum of these mice. Finally, the researchers also showed that mitochondrial function was restored in mice who received hASC injections.
Overall, this study captures the significant potential of hASC to provide successful therapies for neurodegenerative disorders like Parkinson’s disease. That the injection of these cells in a mouse model of Parkinson’s led to both behavioral and physiological improvements in mice demonstrates the great promise for stem cell therapies, and in this context, particularly for therapies developed from adipose-derived stem cells.

In their article, Neurogenic differentiation of murine and human adipose-derived stromal cells, Kristine Safford and colleagues provide evidence for a new candidate for brain therapies. Much of our body’s tissue is able to regenerate to repair itself following injury. However, brain tissue, or neural tissue, does not have this capacity. It has therefore been a priority for medical researchers to identify strategies for repairing damaged brain tissue.
Certain cells, such as embryonic stem cells, can be treated so that they turn into brain cells. However, because it is difficult to access these types of cells, there has been an ongoing search for other ways to create neural tissue for therapeutic purposes. In this publication, the researchers share their finding that fat tissue, or adipose tissue, from adults, may be able to serve this function. Here, the researchers demonstrate that they were able to induce adipose-derived stem cells to undergo alterations that resulted in cells resembling brain cells, or neurons. The researchers were able to change both the shape and chemical features of adipose-derived stem cells so that these aspects of the cells were consistent with those of normal neurons.
This study provides a new therapeutic candidate for brain injury. Ongoing research that aims to determine whether adipose-derived stem cells can be used to develop mature neurons that function appropriately as neurons will clarify whether adipose-derived stem cells will indeed eventually be able to be used to treat specific brain injuries or abnormalities.

More research coming from the University of Utah Health Sciences department shows tremendous improvements in mice treated with human adult stem cells. The report (full article here) shows that mice with a condition very similar to Multiple Sclerosis (MS) were not only able to walk again but able to run within 14 days of treatment and 6 months later showed no signs of regression.
“Results from the study demonstrate the mice experience at least a partial reversal of symptoms. Immune attacks are blunted, and the damaged myelin is repaired, explaining their dramatic recovery.”
“We want to try to move as quickly and carefully as possible,” Lane continued. “I would love to see something that could promote repair and ease the burden that patients with MS have.”
So far this news seems to be in lockstep with current Stemedix adult stem cell treatment of human patients that are reporting similar levels of progress and symptom loss. With every treatment we are continuing to monitor the progress, collect appropriate data from our patients, as well as fine tune our process accordingly so that they get the largest possible benefit from our stem cell treatment.
“I think we all can agree this is exciting news for stem cell research but much more so for the patients with degenerative diseases that Stemedix treats every day.” said Erik Consorsha, a Stemedix representative who continued, “Its very encouraging to have university level scientific researchers seeing the same results we are.”
