Figure 1. Mechanical stretch intensity influences the proliferation and apoptosis of VSMCs. (A) Apoptosis of VSMCs was detected by flow cytometry. (B) The cell cycle of VSMCs was detected by flow cytometry. (C) Quantitative analysis of apoptosis in VSMCs. (D) Quantitative analysis of the cell cycle in VSMCs. (E) The proliferation of VSMCs was detected by Cell Counting Kit 8 (CCK-8). Values are expressed as means±SD. *P < 0.05, **P < 0.01, compared with 0% elongation group.
