lamellipodiumn.

1970 M. Abercrombie et al. in Exper. Cell Res. 60 443/2 We have therefore three kinds of structures..the thin anterior tip of the cell which..may protrude or withdraw..the ruffle formed by the bending upwards of this anterior tip..and the vertical ruffles that appear directly on the dorsal surface behind the anterior edge. We propose for future discussion to introduce the term lamellipodium, on the analogy of filopodium, for such thin, sheet-like, mobile, commonly transitory projections from the cell.

1973 Developmental Biol. 30 75/1 A lamellipodium is a large, flattened cell extension... This strictly morphological usage differs from that of Abercrombie et al...but has, I believe, wider application.

1978 Sci. Amer. Apr. 74/1 When a 3T3 cell comes into contact with another 3T3 cell or with a nonmigrating cell, the sheetlike lamellipodium at the front end of the cell ceases its ruffling movement.

1987 Developmental Biol. 119 45/2 Lamellipodia..are responsible for firm adhesion of the neuron to its substratum.
