Abstract
Hemocytes were isolated from Periplaneta americana (L.) adults and prepared by the critical-point method for examination with a scanning electron microscope (SEM). Micrographs obtained from intensity, and Y-modulation of the SEM beam revealed mainly spherical or broadly ellipsoidal hemocytes, 6-8 μ. diam, with irregular surfaces composed of small evaginations and indentions. Hemocytes which began to migrate exhibited slender processes which projected radially from a well-defined cell margin. In an advanced state of presumed motility, the pseudopodlike extensions had coalesced into a reticulated, stellate-tipped, membranous veil. The externally noted similarity of all examined hemocytes supports the concept of very few or 1 basic cell type with a capacity for several functional states.
