From basketball to handball, rugby to American football, teams in a variety of sports huddle together to agree tactics in secret. Cells, too, can huddle to communicate within a restricted group, scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have found. The study, published today in Nature, is the first demonstration that the way cells organise themselves influences their ability to communicate. The researchers propose that this strategy, which they discovered in developing zebrafish, could be much more widespread, influencing processes like wound repair, organ formation and even cancer.
