Microscope slide showing a section of mammal lymph node stained with silver stain to show reticular fibers.

Mammal Reticular Tissue Slide, 7 µm, Silver Stain. Reticular tissue is a type of loose connective tissue that is primarily composed of reticular fibers (type III collagen fibers). Students can use this slide, a section of mammal lymph node stained with silver stain, to easily identify the long, branching reticular fibers. This type of tissue is found in bone marrow and lymphatic tissues.
