Developmental Biology: Long-Range Signalling By Touch, Nature
Excerpts: One of the best-known mechanisms involves the production and release of signalling proteins, which convey instructions over long distances about how cells should behave and what they should become. Information can also be exchanged through the direct contact of cells with their immediate neighbours. Nerve cells are specialized for communicating over long distances by touch. (...) they can send longer-distance signals that are still mediated by direct contact. To do so, the cells grow finger-like protrusions called filopodia. (...) reveals a new tool by which tissues can be patterned during development.
