Are there model cells (in the sense of model organisms) in the human body (other than E.coli) about which is known most (with respect to structure, function, metabolism, gene expression, ...) and to which I can refer when asking questions about "typical cells" (which per se don't exist). The other way around:
About which cells (added: normal and mature) in the human body do we know most?
(Maybe there's a cell in the rat we know more about, but also know/believe that it is very similar to a human cell? Which one, then?)
Having asked this, I'd also like to know, about which neurons in the human brain is known most, e.g. about "pyramidal cells in cortical layer IV"?
