Lymph Node (Silver reticulum) [#36]: The reticular fibers are selectively stained brown-black by the silver reticulum stain and are arranged in loose spidery meshworks. These reticular fibers may be observed to blend with the collagenous fibers of the capsule and trabeculae, and they are usually intimately associated with stellate reticular cells (that are unstained in this section). Note also that the meshwork of reticular fibers criss-cross the various sinuses and are denser in the vicinity of blood vessels.
