plasmatocyte granular plasmatocyte TGMA:0001853 TGMA:0001853 The granular plasmatocytes showed elongated or circular nucleus displaying a scattered mass of heterochomatin, and in some cells a large nucleolus could be observed. The cytoplasm was rich in RER and Golgi system. The numerous granules seen by LM were observed by EM with no limiting membrane, similar to cellular inclusions, showing a homogeneous matrix and located among endoplasmic membranes. Some of the inclusions show an electron-dense core, possibly indicating a dual constitution. default_namespace
