The distribution model of GM130 (Golgi complex) and MitoTracker (mitochondria) staining during E. modestus spermiogenesis.

The GM130 and the MitoTracker staining patterns are concordant so they are both represented by orange dots. (A) Early stage of spermiogenesis. (A) Early stage of spermiogenesis. GM130 and MitoTracker localize in the cytoplasm near the periphery of the nucleus. (B) Middle stage of spermiogenesis. GM130 and MitoTracker localize near the LCx and along one side of the nucleus as the nucleus gradually deforms. (C,D) Late stage of spermiogenesis. GM130 and MitoTracker localize in the LCx and in the proacrosome near the AFS, (E) Mature stage. GM130 and MitoTracker localize in the acrosome. M: mitochondrion, N: nucleus, C: centriole, MT: microtubule, MF: microfilament, LCx: lamellar complex, AFS: acroframosome.
