Primary source abstract: "Two fundamental parameters of the highly dynamic, ultrathin lamellipodia of migrating fibroblasts have been determined-its thickness in living cells (176 +/- 14 nm), by standing-wave fluorescence microscopy, and its F-actin density (1580 +/- 613 microm of F-actin/microm(3)), via image-based photometry." |
| Comments |
P.1 right column top paragraph: "Estimates of actin filament concentrations in lamellipodia range from 700 µM, based on filament counts from electron microscopy [ref 18 BNID 112789] to 1600 µM, derived from the comparison of the phalloidin label intensities of single filaments and lamellipodia of fixed cells [primary source 19 BNID 112789]. The latter authors concluded that the G-actin concentration at the lamellipodium tip was in the range of 8 µM, based on in vitro rate constants for polymerization [primary source 19]." |
