Average number of filopodia and filopodia containing Arp2/3 complex per cell.
Average number per cell | 15 minutes | 30 minutes | 60 minutes |
Filopodia | 11.7 (± 2.5) | 14.1 (± 1.3) | 17.3 (± 3.1) |
Filopodia containing Arp2/3 complex | 3.2 (± 1.4) | 3.9 (± 1.4) | 7.0 (± 0.4) |
Percentage | 27.4 | 26.2 | 40.5 |
Cells were spread on fibronectin for the ties indicated before fixation. Counts are from 3 independent experiments and are ± standard deviation. 15 minutes n = 73, 30 minutes n = 50, 60 minutes n = 30.
