[Histonet] Histo arcania ... Reticulum vs Reticulin

[Morken, Timothy]

Here is a bit more on the terms

this article gives some background on  Reticulin vs Reticulum

http://en.wikipedia.org/wiki/Reticular_fiber

Briefly, "Reticulin" refers specifically to collagen III. "Reticulum" is an old term that referred to generalized staining of "reticular fibers" and at that time they had no idea of the varieties of collagen. Since the silver stain has been shown to be non-specific the term "Reticulum" may be more correct for the generalized staining.

There is only a semantics difference. "Reticulum" is a connective mesh holding together some organs components such as liver, spleen, lymph nodes and bone marrow. In the German literature is called "glitterfassern" and many silver stains, such as Gomori, are specific for it.
"Reticulin" is used either to refer to the "holding mesh" or to the stain, especially when dealing with bone marrow specimens.

Oh Great Histonet, how do you describe the difference, if any, between the terms "reticulum" and "reticulin."
