The increase of oligodendrocyte lineage cells by iVEC transplantation in the white matter infarct was not abrogated by FTY720 treatment. A Immunohistochemical images for Olig2 in vehicle-injected (Vehicle), iVEC-transplanted (iVEC), FTY720-treated (FTY), and FTY720-treated and iVEC-transplanted (FTY + iVEC) groups at day 14. Nuclei were stained by Hoechst 33342. Scale bar: 50 µm. B Quantification of Olig2⁺ cells in each group at day 14. All data are expressed as mean ± SEM. n = 5 in each group. ^**p < 0.01. ns, no significant difference. These experiments were repeated three times, and similar results were obtained each time. Typical experiments are shown here
