ResumoHemopoiesis in the Decapod crustacean Carcinus maenas occurs in the lymphocytogenic nodules of the gizzard walls. All blood cells, therefore, erive from a single cell line which proliferates in the nodules. The stem cells are called hemoblasts; they differentiate into circulating hemocytes and into cyanoblasts. Four kinds of homocytes have been identified: one agranulated and three different granulated cell types. The cyanoblasts are non-circulating blood cells. Their differentiation into mature cyanocytes is characterized by the synthesis and the accumulation of hemocyanin. The accumulated protein is probably released into the blood by a process similar to holocrine secretion.
