A portion of the previous post has been enlarged and also pseudocolored in photoshop. The ribosomes from this portion of an hepatocyte are colored purple, this is mainly to emphasize that whatever these vesicles are in the cytoplasm of the rescued mice do have some kind of protein being produced.  The portions of the vesicle membrane that are occupied by ribosomes is not that great, when found, too, they assume a position as if a string of 4-8.  The vesicles in tandem, themselves are colored bright yellow.  The contents of the vesicles needs no coloring it is very electron dense and likely to contain iron, be iron, or some other combinations of metals.

On the left hand side of the lowest vesicular blip, find three very nice ribosomes, but the remainder of the vesicle has but one or two additional ribosomes about the periphery.
