Further study of the chromatoid body in rat spermatocytes and spermatids.
Ultrastructure of the chromatoid body in rat spermatocytes and spermatids was studied by transmission electron microscopy. The following was found: 1. electron dense granules, 72.1 +/- 14.73 (SD) nm, that appeared to be both primary (assembling) and end (disassembling) structural subunits in the biogenesis of the chromatoid body, 2. relationship between chromatoid body and cytoplasmic microtubules, 3. ribbon-like structures and aggregates of 25 nm granules. The discussion focuses on a) a probable sequence of formation and breakdown of the chromatoid body, and b) the chromatoid body as an example of a common cellular design involving an interrelationship of dense material-smooth membranes-microtubules.
