- Reticular fibers
- Hepatocytes (parenchymal cells that are supported by the fibers)
- The main constituent of this tissue is the fiber type: Reticular fibers .
- These reticular fibers form a 3 dimensional framework (stroma) that the functional cells  (parenchyma) of the organs sit on.
- Cell types include:
- White blood cells
- Mast cells
- Liver cells (called hepatocytes)
- Forms a soft internal skeleton to support the cell types.
- lymph nodes
- Bone marrow
