Control animal (neg 5936 block 8830 baboon, f, #23, right lobe of the liver, control bx, modified Karnovsky’s fix, 1% osmium tetroxide, Epon 812, (9 28 1977)). There are a lot of smooth vesicles in this sample and just a little bit of RER, three lipid droplets, and part of a bile canaliculus, possible the space of Disse in the very upper most right part of the image, mitochondria look pretty normal) I was looking for desmosomal-mitochondrial tethers and found this pretty nice desmosome and I pseudocolored the plasmalemma from the two adjacent hepatocytes present at the desmosome purple. There was a clear the “outer dense layer” of the desmosome (which i think is so unfortunately named “outer” and should have been named “inner dense layer” of the desmosomal complex). It had a particularly “loopy” appearance that I highlighted in orange. Top image is the original micrograph (two hepatocytes) and box is the area enlarged in the figure below with a desmosome).
