Stem cells multiple sclerosis

Stem cell transplantation to replenish glial cells lost in multiple sclerosis 512... 

Some aspects of multiple sclerosis are reflected in the animal model experimental autoimmune encephalomyelitis, which is induced by immunization of susceptible animals with appropriate encephalogenic proteins or peptides. In these animals, if cultured adult stem cell neurospheres are injected into the bloodstream, injected cells can find their way to damaged portions of the nervous system and improve function in mice. How the injected cells augmented the recovery process is unclear. One possibility is that cells recruited to the lesions differentiated into oligodendrocytes and generated new myelin sheaths, but this seems unlikely in the face of ongoing cellular destruction. 

Microchimerism and Stem Cell Transplantation in Multiple Sclerosis... 

The use of neural stem cells in remyelinating therapy has been explored by many researchers. Pluchino et al. (2003) successfully used adult neural stem cells to promote functional recovery in a multiple sclerosis model. Transplanted neural stem cells showed the ability to selectively reach the demy-elinating areas, where they differentiated into axon-ensheathing oligodendrocytes and achieved extensive remyehnation (Pluchino et al., 2003).

However, with these challenges in mind, stem cell therapy remains one of the best natural candidates to help heal the human body. Despite the many challenges, many scientists believe that cell therapy will revolutionize medicine. These cell therapies may one day offer cures for cancer, Parkinson s disease, diabetes, kidney disease, multiple sclerosis, cardiovascular disease, and symptoms of stroke. Cell therapy may also hll a tremendous need for chronic pain management and traumatic brain injury (TBI). 

However those capsules are not limited to diabetes they have other applications with hepatocytes and stem cells. Applications of stem cells for therapy of neurological conditions, such as Parkinson s disease, Alzheimer s disease, multiple sclerosis, or stroke, are promissory therapies for the irreversible damage of the central nervous system produced in these cases. In that sense, the transplantation of stem cells into the mouse brain, and MRI of the cells both in vivo and post-mortem have been analyzed [87]. Also labeling of stem cells with superparamagnetic iron oxides (SPIOs) have been developed for using MRI to visualize these cells in myocardial infarct [88].
