In recent years, there have been a number of advances in stem cell research and in the various ways that these cells can be best employed to improve the health of patients. One of the medical areas that shows promise for stem cell therapies is orthopedics, with stem cell therapies being developed to help with tissue, cartilage, and bone repair. A recent review by Anish Majumdar and colleagues conveyed the progress that has been made specifically in the use of stem cells for the repair of cartilage in osteoarthritis.
Patients with osteoarthritis experience degeneration of their connective tissues, which progresses as they get older. While osteoarthritis is often diagnosed in older patients, athletes also often endure osteoarthritis after injuring themselves while playing sports. In osteoarthritis, tissue known as articular cartilage is particularly susceptible to injury and unfortunately does not heal as well as other tissues because it does not have the vasculature required to supply the tissue with the nutrients required for significant growth and recovery.
When articular cartilage is damaged, surgery is often employed in an attempt to correct the damage, and pharmaceuticals are sometimes prescribed for discomfort. However, these interventions do not tend to achieve satisfying results. Because bone marrow stromal cells, or bone marrow-derived mesenchymal stem cells, naturally differentiate into the cells that make up cartilage, it has been suggested that these stem cells could improve outcomes for those with osteoarthritis.
These particular stem cells have other advantages, including that their isolation is relatively simple and that they easily proliferate, adds to their attractiveness as a candidate for cartilage repair. Their ability to suppress the immune system and prevent inflammation makes them more likely than many other cell types to be safe when added to the cartilage. As such, according to this review, a number of researchers have reported that their injections of these stem cells in patients with osteoarthritis have not caused any problems related to safety.
These findings include stem cells leading to improvements in clinical symptoms and quality of life in those with osteoarthritis, as well as the filling of the defect area and reduction in pain.
Researchers have also reported that these stem cells are effective from a therapeutic standpoint when administered to osteoarthritis patients. A number of specific findings on the success of bone marrow-derived mesenchymal stem cells in cartilage repair demonstrate that stem cells could revolutionize therapeutic strategies for this type of tissue damage. These findings include stem cells leading to improvements in clinical symptoms and quality of life in those with osteoarthritis, as well as the filling of the defect area and reduction in pain.

More research recently published in Brain Research titled “Intravenous transplantation of bone marrow-derived mono-nuclear cells prevents memory impairment in transgenic mouse models of Alzheimer’s disease.” shows how stem cell therapy may be a promising technique for preventing the cognitive decline associated with Alzheimer’s disease. Because of the potential for stem cell therapy to help in neurological disorders, it is already being used in clinical trials for certain afflictions, such as stroke. Here, the scientists demonstrate how the implantation of bone marrow-derived mononuclear cells (BMMC‘s) can both reduce the deposits of Amyloid-β (Amyloid beta), the protein that characterizes Alzheimer’s disease, as well as improve memory in a mouse model of the disease.
“Together, our results indicate that intravenous transplantation of BMMC‘s (bone marrow-derived mono-nuclear (stem) cells) has preventive effects against the cognitive decline in Alzheimer’s disease model mice and suggest a potential therapeutic effect of BMMC transplantation therapy.”
Amyloid beta, which is observed in the brains of those with forms of dementia including Alzheimer’s disease, has previously been shown to lead to cognitive deficits. Many attempts to develop preventions and treatments for Alzheimer’s disease have thus targeted this specific protein. However, none of these efforts have yet been clinically successful. Our growing understanding of stem cells and their therapeutic applications has opened up a promising new avenue for Alzheimer’s disease research.
The researchers chose to specifically use BMMC‘s because of their heterogeneity and because they are relatively easy to purify and do not requiring culturing. They implanted these cells in DAL mice, which have mitochondrial dysfunction similar to that observed in Alzheimer’s disease. In these mice, BMMC‘s prevented the aggregation of Amyloid beta and led mice to perform as well as normal mice in a spatial and learning and memory task. Impressively, these effects were observed even when cognitive decline had already begun in DAL mice.
This research strongly supports the idea that stem cells could help prevent the physiological and behavioral manifestations of Alzheimer’s disease. As research moves into the clinical phase, the specific ways that stem cells can aid in dealing with this devastating disease.

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.”
