Injection of the patient’s own hematopoietic stem cells promotes
restoration of injured spinal cord and disrupted function of the peripheral
nervous system.
These are results of clinical experiments carried out by the specialists
of Russian State Medical University and the Clinic of Rehabilitation
Intervention Neurology and Therapy "NeuoVita".
The experiment involved 67 patients of different ages with severe spinal
cord injuries. The patients were divided into two groups. The ten patients to
whom cellular therapy was contraindicated for different reasons formed a
reference group. They only underwent rehabilitation. The rest of the patients,
on top of rehabilitation, underwent at least two injections of their own
hematopoietic stem cells. Before that they had received a course of
injections of granulocytic colony-stimulating factor that ensured additional
production of stem cells and their coming out of the marrow into blood
vessels. The cells were collected at the blood separator, frozen and used as
needed. Each patient was injected about 5 million cells into the vertebral
column. The course was repeated to some patients.
The spinal cord trauma impacts both the work of the spinal marrow itself
and that of the peripheral nervous system. Several years after the trauma,
the nerves gradually degenerate and finally perish. Rehabilitation would not
help in this case, the researchers made certain of that again by the example
of the reference group, the state of which had not changed. The cellular
therapy helped to a significant part of the patients (61 percent). Their
muscle activity increased, movements and sensitivity intensified, pelvic
organs’ function improved.
After the first cell transplantation, these changes were of minimal extent,
however, the second transplantation supported by intensified rehabilitation
has done its part. After the second injection of cells was perfomed, many of
the 33 patients were able to stand on their knees and to move with the help
of "go-carts". It should be noted that they had not experienced the slightest
improvement for several years.
The ecouraging clinical finding was confirmed by the electroneuromyography
data that allows to assess quantitatively the muscle response to nervous
stimulation. After cell transplantation, there was an increase of the muscle
response amplitude to activation of motor nerve fibers of peripheral nerves.
This data is an indirect evidence that cellular therapy promotes spinal cord
regeneration. Having summarized the findings, physicians concluded that
transplantation of the patient’s own hematopoietic stem cells is secure and
efficient in conjunction with other treatment modes.
