Mechanical stress induces a local concentration of polymerized actin in mechanically stressed cells
| Cell treatment | Mean cell fluorescence | Maximum local fluorescence | Number of studied cells |
|---|---|---|---|
| None (control) | 51.4 ± 2.7 | 81.6 ±5.6 | 11 |
| Pipette aspiration | 55.7±2.6 | 128±8.5 (P<0.001) | 14 |
Eleven control cells and fourteen cells that had been subjected for 4 minutes to micropipette aspiration were fixed and microfilaments were stained with NBD-phallaciding. Mean cell fluorescence and maximum pixel fluorescence were then recorded under the same conditions. Mean values are shown (using arbitrary units) ± Standard Error.
