Spermatogenesis of Double-Mutant dox; nmy Is Normal
(A–C) TEM images of sperm maturation.
(A) Early post elongation stage of a spermatid head (upper) and tail (lower). Normal nuclear condensation can be seen apposed to rows of microtubules (white arrowheads), while nucleoplasm is eliminated (v).
(B) Late post elongation stage of spermatid heads with homogeneously condensed nuclei (upper left and right). Also note the normal head-tail alignment (middle) and the tail (lower right).
(C) Post individualization stage of a sperm bundle with 61 normal tails and one degenerated tail in the waste bag (WB).
(D) DAPI images of 64 spermatid heads in a bundle at the stage of post elongation.
Abbreviations used in annotation: AX (axoneme); BB (basal body); mM (minor mitochondrial derivative); MM (major mitochondrial derivative); mS (minor strip); MS (major strip); MT (microtubule); WB (waste bag). Scale Bars: 500 nm (A–C); 20 μm (D).
