当虎库蚊精子细胞开始伸长时，细胞核在其表面出现核膜内陷。这些内陷的直径均匀为 0.3 μm。它们与细胞核的包膜分离并形成球形核内囊泡。在古老的精子细胞中，这些囊泡被囚禁在浓缩的染色质中。精子也拥有这些卵圆形的囊泡。当精子发生过程中核体积减小时，这种囊泡形成过程使得核表面缩小。 © 1993 Wiley-Liss, Inc.
When the Culex tigripes spermatid begins to elongate, the nucleus exhibits on its surface invaginations of the nuclear envelope. These invaginations have a uniform diameter of 0.3 μm. They separate from the envelope of the nucleus and form spherical intranuclear vesicles. In the old spermatids these vesicles are imprisoned in the condensed chromatin. The spermatozoon also possesses these vesicles which are then ovoid in shape. This process of vesiculation permits the diminution of the surface of the nucleus when it decreases in volume during spermiogenesis. © 1993 Wiley‐Liss, Inc.
