Stem cell therapy in Bangkok Thailand for spinal
injury
For the first time in the United States, stem cells have been directly
injected into the spinal cord of a patient, researchers announced
Thursday. There are various other trials and tests going on around
the world with stem cell treatment for spinal cord injuries.
Researchers at Karolinska Institutet have shown how stem cells,
together with other cells, repair damaged tissue in the spinal cord.
The results are of potential significance to the development of
therapies for spinal cord injury.
There is hope that damage to the spinal cord and brain will one
day be treatable using stem cells (i.e. immature cells that can
develop into different cell types). Stem cell-like cells have been
found in most parts of the adult human nervous system, although
it is still unclear how much they contribute to the formation of
new, functioning cells in adult individuals.
A joint study by Professor Jonas Frisén's research group
at Karolinska Institutet and their colleagues from France and Japan,
and published in Cell Stem Cell, shows how stem cells and several
other cell types contribute to the formation of new spinal cord
cells in mice and how this changes dramatically after trauma.
The research group has identified a type of stem cell, called an
ependymal cell, in the spinal cord. They show that these cells are
inactive in the healthy spinal cord, and that the cell formation
that takes place does so mainly through the division of more mature
cells. When the spinal cord is injured, however, these stem cells
are activated to become the dominant source of new cells.
The stem cells then give rise to cells that form scar tissue and
to a type of support cell that is an important component of spinal
cord functionality. The scientists also show that a certain family
of mature cells known as astrocytes produce large numbers of scar-forming
cells after injury. "The stem cells have a certain positive
effect following injury, but not enough for spinal cord functionality
to be restored," says Jonas Frisén. "One interesting
question now is whether pharmaceutical compounds can be identified
to stimulate the cells to form more support cells in order to improve
functional recovery after a spinal trauma."
With all the promising data coming from the various stem cell trials
for spinal cord injury, Bangkok Thailand might be a prime location
in the future to have spinal cord injuries treated through stem
cell therapy.
