I would vote for "No difference."

Reticulum means a network.

Reticulin is the protein found in a type of connective tissue, 
particularly those found in reticular fibers. 
(Also called Type III collagen.)

Reticular fibers form a loose network.

Reticular fibers are stained with argyrophilic silver stains. 
These stains do not stain the reticular fiber protein (reticulin), 
but rather stain the proteoglycan portion of the reticular fibrils. 

To get around this confusion in our lab, we just call it the
"Retic Stain."    :-)
