Each and every cell has an identical inventory of DNA. Thus a liver
cell has the same "kit" as a retinal cell or a neuron. So cell types
that are labeled according to their primary function, still retain the
potentiality to employ as needed what other cells do in a big way. I'm
inclined to think that any cell would do exactly that whenever useful, by (of course) turning on the appropriate genes at appropriate
levels of expression and in appropriate combination.<br>
<br>
Now I'm unfamiliar with the cellular mechanism(s) for photon emission,
and I only mention the retinal cell as an example of a cellular
photo-sensitive capability. I would be surprised to not find multiple
modes of cellular photo-sensitivity in addition to the retinal forms,
with the "appropriate" form employed as a standard for inter-cellular
"communication". All encoded in the genes of course. <br><br> Regarding <font face="Arial" size="2"><span lang="EN"><span>"...a
scientific explanation for the relationship between cells...", a "how" explanation would involve describing the conditions leading to the communication and the communication itself</span></span></font><font face="Arial" size="2"><span lang="EN"><span> (in cell one)</span></span></font><font face="Arial" size="2"><span lang="EN"><span>, and the consequences of the communication</span></span></font> (in cell two), and a "why" explanation would involve clarifying where the value lies for the cells and the organism, for the communication. I can't do the first, but I'll take a "well, duh!" amateur shot at the second.<br>
<br>Adjacent cells work together. Communication enables efficient cooperative function. (I said it was "Well, duh!")<br><br>I could leave it there, and retire from the field without significant embarrassment. But what fun would that be? <br>
<br>I still think -- and this suspicion is growing not shrinking -- that research will eventually uncover a largely unexpected, and unexpectedly complex suite of "behaviors" at the cellular level.<br>Yes, "behaviors", as in the kind of things we associate with (please forgive me) consciousness. That this cellular consciousness is mediated by quantum effects, and that the larger form of consciousness with which we are familiar is emergent from the combined consciousness of all the cells. So it is that I suggest (and with only a bit of a sly wink) that inter-cellular communication, beyond utilitarian content, may also be "social talk", cellular gossip, a handshake, a wink, a pat on the back.<br>
<br>Yeah, yeah, I know: anthropomorphic projection. Maybe. Or maybe not.<br><br>So why exactly is it that they call this sticking your neck out? Shouldn't it be sticking your head out?<br><br>Best, Jeff Davis<br>
