Compressibility vs cell size for A549, HASM, and MCF-7 cells. The compressibility is measured for A549: 4.33 ± 0.13 × 10−10 Pa−1 (n = 114), for HASM: 4.04 ± 0.24 × 10−10 Pa−1 (n = 93), and for MCF-7: 3.99 ± 0.16 × 10−10 Pa−1 (n = 191); the cell size is measured for A549: 15.2 ± 2.2 μm (n = 114), for HASM: 13.6 ± 1.7 μm (n = 93), and for MCF-7: 18.7 ± 2.8 μm (n = 191).
