SSS containing serum improved OGD-insulted cerebral endothelial cells viability after tPA administration. A Toxicity evaluation of SSS containing serum on bEnd.3 cells under normal conditions by CCK8 assay. B The determination for optimal dose of SSS containing serum on OGD-insulted bEnd.3 cells. *p < 0.05 vs 0%. C Toxicity assessment of tPA on bEnd.3 cells under normal conditions. D The determination of toxic dose of tPA on OGD insulted bEnd.3 cells. *p < 0.05 vs 0 μg/mL. E The SSS containing serum protected the viability of OGD insulted bEnd.3 cells suffered from tPA. *p < 0.05 vs OGD; #p < 0.05 vs tPA
