P.1 right column top paragraph: "Estimates of actin filament concentrations in lamellipodia range from 700 µM, based on filament counts from electron microscopy [primary source 18] to 1600 µM, derived from the comparison of the phalloidin label intensities of single filaments and lamellipodia of fixed cells [primary source 19]. 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]." Primary source [18] studied human glia cells. Primary source [19] studied mice 3T3 fibroblasts. |
