One cell from the liver of a control (sort of) for the Gclc ko mouse (that is that it had one wild type allele for the gene for turning on albumen synthesis (WC/ii  ) which rescues the would-be Gclc-/- mouse from death. This hepatocyte is not really remarkable to me but it did have this great tangential section of the hepatocyte nucleus and the nuclear pores were just scattered all over the area sectioned making the uniformity of the condensed chromatin areas surrounding the pores very visibly7 consistent.  It was so nicely consistent that I decided to try an afix a casual, but hopefully useful, measurement to that exclusion zone, at least in the this particular animal model.

So, that distance (based on the 27nm size of a mammalian ribosome turns out to be the following:  mean distance, 58nm.  From the original scanned image 58 nm+/- 16nm. That makes the space around the nuclear pore sort of a ring, of about 55 nm. Black line composit measurements, see bottomright. Red dot = one ribosome,
