Comparison of cytotoxicities of HQ on BM-HSC and YS-HSC.

<p>Cells were exposed to increasing concentrations of HQ after 24 h liquid culture. (a) Cell viability was measured by the trypan blue exclusion assay. The initial cell amount used was 1×10⁵/ml. Relative cell viability was represented as the percentage of viability of treated group over the control. (b) Cell viability was determined by the CCK-8 assay. Left: Viability of BM-HSC and YS-HSC; right: Relative viability of BM-HSC and YS-HSC over control. Data represent means ± SDs (n = 3).
