Abstract
|
|
|
|
The hemocytes of Drosophila melanogaster were observed with electron microscope, and five types of the cells were identified; prohemocyte, plasmatocyte, granular cell, crystal cell and oenocytoid, accounting for about 5%, 35%, 45%, 10%, 5% respectively of total cell numbers. Prohemocytes are characterized by a low concentration of intracellular organelles. Plasmatocytes are spindle or oval in shape and have relatively plenty of organelles and lysosomes. Granullar cells are the most polymorphic. They have numerous pseudopod-like projections and contain various granules and inclusions. In this cell type, intracellular organelles are fully developed. Crystal cells are characterized by numerous crystals composed of fine granules arranged regularly. Oenocytoids are the largest one among all cell types and contain relatively developed organelles.
