Cells released in vitro from the embryonic yolk sac of the stick insect carausius morosus (BR.) (PHASMATODEA : HETERONEMIIDAE) may include embryonic hemocytes

The embryonic yolk sac and the adult dorsal vessel of the stick insect Carausius morosus (Br.) (Phasmatodea : Heteronemiidae) were shown to release a number of cells that appear morphologically similar to circulating adult hemocytes. Like adult hemocytes, these cells reacted positively when tested f...

Description
Summary:The embryonic yolk sac and the adult dorsal vessel of the stick insect Carausius morosus (Br.) (Phasmatodea : Heteronemiidae) were shown to release a number of cells that appear morphologically similar to circulating adult hemocytes. Like adult hemocytes, these cells reacted positively when tested for both phenoloxidase activity and a monoclonal antibody specifically raised against a vitellin polypeptide. Based on this evidence, it is suggested that yolk sac-released cells behave as potential embryonic hemocytes. A model is thus proposed whereby the yolk sac might host a number of hemopoietic stem cells on their way to the dorsal vessel, and in so doing, it may temporally act as an embryonic hemopoietic organ.
