Hey all,

We are having a debate in the office about which is the correct term for sections? Would they still be in vivo or are they now classed as ex vivo/in vitro?

What do you mean by "sections"? Seems in vitro and ex vivo are pretty inconsistent with in vivo.

It seems to me that since the tissue is sectioned and experimented upon outside of the animal, ex vivo should be used. In contrast, fluorescence detection methods used to visualize protein expression within a living animal should be in vivo. Nevertheless, every paper I have read that describes sectioned tissue immunohistochemistry uses in vivo, rather than ex vivo.

Science is simply common sense at its best that is rigidly accurate in observation and merciless to fallacy in logic.
