Here are six observations:
1. Researchers studied the olfactory bulb neural stem cells in rats with SCI. They divided the rats into a control group, sham group and treated group, and studied their tissue weekly for two months.
2. The study’s goal was to ascertain whether the olfactory bulb neural stem cells could restore lost sensory motor functions in rats with SCI.
3. All the rats experienced successful engraftment. The transplanted cells experienced a 30 percent survival rate.
4. The neural stem cells survived for more than eight weeks after engraftment.
5. The engrafted cells were found in gray and white matter of the cord, and demonstrated no abnormal morphology or mass formation.
6. The engrafted cells did not restore lost sensory and motor functions, based on the Basso, Beattie and Bresnahan test.
