Les cellules animales utilisent divers mécanismes pour communiquer à distance. Elles peuvent transmettre des informations en émettant des molécules qui ciblent des récepteurs spécifiques ou utiliser de longues extensions cellulaires telles que les axones. [Des chercheurs] ont étudié le rôle d'autres prolongements cellulaires : les cytonèmes. Identifiés en 1999 chez la drosophile, ils sont constitués de filaments d'actine et peuvent s'étirer sur des distances de 50 à 100 cellules.
