This is so awesome, just read part of this article by cheutin et al_awesome nucleolar diagram and view the TEMs and diagrams, were that I were beginning a career in TEM tomography, i would be in heaven. But 40 years too early.  So at best, is to take the new information and correlate it with studies from the past, making use of the data that I have and thousands of electron micrographs to play with.

TO begin with, 14CoS nuclei and nucleoli with some bar markers, just getting acquainted with the possibilities for labeling these structures. So here is the image from a previous post, and the segment enlarged with the two cajal bodies, tiny red circle is the size of a ribosome. Nucleolar structures I have not measured yet, but according to the publication by Cheutin et al, linked above, these will be similar and important in the pre-apoptotic hepatocyte nuclei found in this mouse line when they are not rescued by administration of oral 2-(2-nitro-4-trifluoromethyl-benzyol)-1,3-cyclohexanedione (NTBC).
