A recent study conducted by US researchers (on Thursday), help embryonic stem cell to grow critical nervous system cell oligodendrocytes. Scientists believed that in future this new nerve cells generated from embryonic stem cells will be able to repair damaged nerves of multiple sclerosis.
Oligodendrocytes produce the myelin sheath that surrounds nerve fibers like wire insulation.
According to experts, the findings represent an important step toward embryonic stem cell-based therapies in general, and also for cell-based therapies for myelination disorders such as MS in particular.
Researchers have definitely layed the groundwork for being able to apply these cells in terms of a therapeutic application.
But as Dr. Su-Chun Zhang of the University of Wisconsin, Madison, who has been studying oligodendrocytes and myelination for nearly a quarter-century, tried to apply the culture conditions painstakingly worked out in rodents to human cells, oligodendrocytes failed to emerge, so experts don’t like to relay on assumptions as human cells not always behave like mouse cells. But they agreed that at least the findings would indeed lead to a laboratory model of the illness’ pathology.
The research was published in the May issue of the journal Development.
