Paraptotic-like cell death during vitellogenesis of Ligula intestinalis. a–e Vitellocytes cytoplasm shows progressive cytoplasmic vacuolation, swollen mitochondria and granular endoplasmic reticulum (asterisks) – features characteristic for paraptosis. b, d The nucleus contains a large nucleolus and the chromatin is homogeneously dispersed. Note: the lack of apoptic characteristic of the nucleus in mature vitellocytes. Scale: a, b: 2 μm; c, d, e: 3 μm
