Fig. 5From: Intracellular localization of vitellogenin receptor mRNA and protein during oogenesis of a parthenogenetic tick, Haemaphysalis longicornisA schema of Vg uptake during oogenesis of parthenogenetic H. longicornis. Synthesized Vgs (Vg-2 and Vg-3) are released from the fat body into the hemocoel filled with hemolymph. The Vgs are taken up by oocytes of stages III, IV and V. Abbreviations: I, stage I oocyte; II, stage II oocyte; III, stage III oocyte; IV, stage IV oocyte; V, stage V oocyte; Vgs, vitellogenins; VgR, vitellogenin receptorBack to article page
