reticular fibres

views updated

reticular fibres (argyrophil fibres) Extremely fine fibres (cells) that form networks around and between cells in many vertebrate tissues (e.g. blood vessels, nerve cells, muscle cells, and several organs). They can be seen when stained with silver salts (hence the name ‘argyrophil’–‘silver-loving’). Their main constituent (reticulin) is also found in collagen fibres, which reticular fibres resemble in some respects (e.g. they are inelastic and are not digested by trypsin).
