在睾丸内注射H3-胸苷后的不同时间间隔，从两只成年狒狒（Papio anubis）中采集活检和睾丸切除术标本。使用PASWeigert-苏木素对Zenker‐福尔马林或布因固定材料进行染色，并使用H.S.R.进行放射自显影。（Harleco合成树脂）涂层技术。大多数生殖细胞的形态特征与其他猴的生殖细胞相似，但步骤9至11中的精子细胞显示出顶体的棘状突起。此外，A型精原细胞显示出与人类A型精原细胞的某些相似性。细胞联合由12个阶段组成，大量的管状横截面显示存在两个或多个阶段。在Papio anubis中，合子期精母细胞在第VIII阶段形成，精子在第V和VI阶段释放。
Biopsy and orchiectomy specimens were collected from two adult baboons (Papio anubis) at different intervals after intratesticular injection of H3‐thymidine. Zenker‐formol or Bouin's fixed materials were stained with PASWeigert‐Hematoxylin and radioautographed using the H.S.R. (Harleco Synthetic Resin) coating technique. Morphological features of most germ cells appeared similar to those of other monkeys, except that the spermatids in steps 9 to 11 showed a spike‐like projection of the acrosome. Also, the type A spermatogonia showed some resemblance to the human type A spermatogonia. The cell associations consisted of 12 stages and a large number of tubular cross sections showed the presence of two or more stages. In Papio anubis, the zygotene spermatocytes are formed in stage VIII, and spermatozoa are released during stages V and VI.
