Histological analysis of silver-stained, i.e. argyrophilic nucleolar organizer regions (NOR).

These are parts of the chromosome that are involved in ribosomal synthesis.

The characteristics of the AgNORs, e.g. size and distribution have been used, to analyse tumours, sometimes as a surrogate of proliferative activity. Not in wide use.
