[Ultrastructural labeling of the chromatoid body and the centriole-associated body using the DNase-gold colloidal...

In Monkey spermatids at different steps of spermiogenesis, the use of DNase-gold complex showed, at the ultrastructural level, a labeling over the chromatin and concomitantly over the chromatoid body, centriole associated body and annular chromatoid body. The results obtained with the DNase-gold complex containing either DNA or actin led to discuss the nature of the substances revealed by the labeling in the cytoplasmic structures.
