At the 2006 Keystone Symposium of Lipid Rafts and Cell Function, lipid rafts were defined as "small (10-200nm), heterogeneous, highly dynamic, sterol- and sphingolipid-enriched domains that compartmentalize cellular processes.
Nun simposio de 2006 sobre balsas lipídicas e función celular, as balsas lipídicas foron definidas como "pequenos dominios (10-200 nm), heteroxéneos, moi dinámicos, enriquecidos en esterol e esfingolípidos que compartimentalizan os procesos celulares.
