title: Further study of the chromatoid body in rat spermatocytes and spermatids.
abstract: 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.
