"Application of the periodic acid-Schiff technique to mouse
testis reveals 16 stages of spermiogenesis. The first 12 of these
stages correspond to one cycle of the seminiferous epithelium,
and have been used to establish the developmental sequences
occurring during germ cell renewal in the mouse (Oakberg, ’56, in this number)....Data showing the progressive disappearance of cell generations
are given in table 1 (BNID 110660). Curves were fitted for disappearance
of each cell type, and time intervals between successive
curves were read at the 50% point. ...When the data of table 2, which are based on repopulation, are treated in a similar manner, the estimate
of cycle length is 8.702 days, with a standard error of .353." See note beneath table |
