2.2 Loose connective tissue

Version française

Section of the mucosa of the larynx stained with Masson’s trichrome.

In this field the connective tissue is loose and shows a few fibres. Some small collagen fibrils or reticular fibres (R) are seen around empty-looking spaces (*).

The main connective tissue cells are the fibrocytes (F) showing fusiform nuclei and a scanty cytoplasm. Underlying the ciliated epithelium (Epi) is a relatively thick layer stained green (red arrow) composed of several extracellular elements that cannot be distinguished from one another, i.e. a thin basement membrane (composed of type IV collagen, proteoglycans, laminin and fibronectin), anchoring fibrils (type VII collagen), reticular fibrils (type III collagen), microfibrils (fibrilin), and type I collagen fibrils.

Some capillaries (Ca) are indicated.
