The PNAS paper by Martin Bergert et al. ("Cell mechanics control rapid transitions between blebs and lamellipodia during migration") is listed as a "Must Read" by the Faculty of 1000 (f1000.com) and is also featured by the Cell Migration Gateway (www.cellmigration.org/).
The article describes how migrating cells switch between irregular bulbs called blebs and little spikes called lamellipodia in order to move.
Congratulations!
