Spatial memory assessment of R6/2 mice following umbilical cord mesenchymal stem cell (UC MSC) transplantation. Untreated R6/2 mice displayed significant impairment in spatial memory at 9-, 10- and 11-weeks of age when compared to WT mice. Mice receiving either low- or high-passaged UC MSCs did not display sparing of this spatial memory task. (Note: *significant from WT) Bar graph represents mean value; error bars represents SEM. SEM, stanrard error of the mean; WT, wild type.
