Figure 3. The Young’s modulus of MLO-Y4 was measured by AFM.

Figure 3

At different indentation depth, the cell stiffiness varies greatly, and with the indentations getting deeper, the Young’s modulus gets smaller. At cell cortex, the Young’s modulus was 6.31 ± 0.49 kPa, 4.18 ± 0.31 kPa, 3.15 ± 0.27 kPa, 2.62 ± 0.24 kPa respectively at 50 nm, 100 nm, 150 nm and 200 nm. At 500 nm, the Young’s modulus decreased to 1.98 ± 0.25 kPa, while at deeper indentations (500 nm–1000 nm), the Young’s modulus changed very slightly.
