Figure 4.
Knockdown of SIRT1 suppresses self-renewal of liver CSCs. (A) Proliferation efficiency was detected in liver CSCs after knockdown of SIRT1 by EdU assay. (B) Graph showed the quantification of EdU-positive cells. (C-D) Colony formation efficiency was determined in liver CSCs after SIRT1 inhibition. (E-F) Sphere formation efficiency was determined in liver CSCs after knockdown of SIRT1. (G-H) SIRT1-inhibition in liver CSCs reduced their resistance to sorafenib and cisplatin. All values presented as mean ± S.D. *p < 0.05, **p < 0.01. Scale bar, 100 µm.
