日本鹌鹑的生精上皮细胞周期的阶段的空间安排进行了研究,准备从每个3鹌鹑的生精小管的三维重建。结果表明,各阶段并非随机分布,而是沿曲细精管呈螺旋形沿着排列。空间上相邻的阶段总是生精上皮周期上相邻的数目。发现了完整的精子发生波,其周期的所有10个阶段都是连续的。然而,在大多数波中,阶段的顺序被调制的发生所扰乱。细胞缔合的面积在4600至41,600 μ m 2之间变化,平均值为+/- s.e.m.。(3只动物)17,902 +/- 2614微米2。参与联合的支持细胞数量范围为4至35个,平均值为+/- s.e.m.。(3只动物)为13.5 +/- 2.8。这些发现支持了我们先前的建议,即鹌鹑精子发生的动力学与哺乳动物的模式基本相似。
The spatial arrangement of the stages of the cycle of the seminiferous epithelium of the Japanese quail was investigated by preparing three-dimensional reconstructions of a seminiferous tubule from each of 3 quails. It was found that the stages were not distributed at random, but were arranged in a wave which spiralled helically along a seminiferous tubule. Adjacent stages in space were always adjacent numbers in the cycle of the seminiferous epithelium. Complete spermatogenetic waves were found in which all 10 stages of the cycle were in sequential order. However, in most waves the sequential order of stages was disturbed by the occurrence of modulations. The area of a cellular association varied from 4600 to 41,600 microns 2 with a mean +/- s.e.m. (3 animals) of 17,902 +/- 2614 microns 2. The number of Sertoli cells involved in an association ranged from 4 to 35, with a mean +/- s.e.m. (3 animals) of 13.5 +/- 2.8. The findings support our earlier suggestion that the kinetics of spermatogenesis in the quail are fundamentally similar to the pattern which has been described for mammals.
