Re: Communication between cells...



Why do they assume that there are only chemical signals? Medical science has demonstrated, for instance, that there are also electrical signals (which is how heart cells are able to beat in unison with each other). So if there are two modes of communication between cells, there's a good possibility that there are more.

HP: I would do the same. The organizational and informational (biosemiotic) approach is growing rapidly. For a quick view see

Interesting link, Howard. Thanks.
 
The first paragraph on the first page jumped out at me:

Signal transduction is the study of how cells control their own and each others' behaviors through chemical signals. Signal transduction research is an intensely active field of biomedical research and is of interest to a broad array of scientists. Science's STKE should be useful to the scientists who specialize in signal transduction, as well as the many scientists who need to follow and apply the current findings of this field even though their primary interest may not be in signal transduction mechanisms themselves.
