Fig. 1

Consecutive stages of vitellogenesis in Ligula intestinalis and details of cytoplasmic inclusions. a An immature vitellocyte. b Formation of shell globule clusters. c Early stage of vitellocyte maturation. d, e Advanced stage of vitellocyte maturation. f Mature vitellocyte with numerous shell globule clusters and lipid droplets. g Mature vitellocyte with shell globule clusters, lipid droplets, GER-bodies and highly vacuolated cytoplasm. Note: progressive cytoplasmic vacuolation. Scale: a, e: 2 μm; b, c, f: 0.2 μm; d: 1 μm; g: 5 μm. Abbreviations to all figures: GB, GER-bodies; GC, Golgi complex; GER, granular endoplasmic reticulum; L, lipid droplet; M, mitochondria; N, nucleus; Nu, nucleolus; SG, shell globules; SGC, shell globule clusters; I, immature vitellocyte; II, early stage of vitellocyte development; III, advanced stage of vitellocyte maturation; IV, mature vitellocyte
