Cell-based therapies, such as transplantation of exogenous cells or stimulation of endogenous cells, for stroke are lacking. Bone marrow-derived cells (BMCs) are a viable option as they allow autologous transplantation and can be mobilized by granulocyte colony-stimulating factor (G-CSF). Cytokines released by BMCs contain neuroprotective properties and stimulate endogenous repair thereby potentially improving outcomes following ischemia. In this animal study, the authors’ hypothesis is that the combination of G-CSF and BMC is more effective than either single treatment in mice subjected to focal ischemia. There were 4 randomly assigned groups: placebo, G-CSF, BMC, and G-CSF and BMC. Ischemia was induced by occlusion of the middle cerebral artery for 30 minutes. Treatment occurred 90 minutes after ischemia induction. Rotarod and cylinder test were used to assess motor performance and forelimb activity, respectively. At 1 or 7 days after ischemia, brains were harvested to assess for ischemic damage by various techniques.
