Little groups of very regularly shaped cells, orsingle cells, are seen lying in the spaces of the network; some of these 178 INFLAMMATION, ORGANISATION, AND REPAIR cells are elongated, others are pear-shaped, whilst others again areirregularly rounded, most of them staining deeply and presentingevidence of rapid proliferation.
