Abstract

The development of the musk gland in house musk shrews aged 0 to 21 days was studied lectin histochemically. On about 3 days of age, the musk gland could be discriminated from surrounding skin. This organ developed markedly on days 3 to 7, and its development continued to 21 days of age. Histologically, on day 1, the bulges that should develop into musk glands were identified in the vicinity of hair germs. On days 3 to 7, these bulges developed markedly, and on day 21 their structure revealed almost the same morphology with that in mature musk glands. We used 7 lectins; ConA, RCA I, PNA, SBA, UEA-I, DBA, and WGA. On day 1, 6 lectins except for WGA labelled the cell of the musk gland. WGA began to label it on day 3. Until 7 days of age, lectins bound to only the cytoplasm of the cell of musk glands. On days 12, however, PNA and UEA-1 labelled the cell membrane equally, and RCA I labeled it on day 21.

摘要

采用凝集素组织化学方法研究了0至21日龄家麝鼩麝香腺的发育情况。在大约3日龄时，麝香腺可与周围皮肤区分开来。该器官在3至7日龄时显著发育，其发育持续到21日龄。组织学上，在1日龄时，在毛胚附近可识别出应发育成麝香腺的凸起。在3至7日龄时，这些凸起显著发育，在21日龄时其结构显示出与成熟麝香腺几乎相同的形态。我们使用了7种凝集素：伴刀豆球蛋白A（ConA）、蓖麻凝集素I（RCA I）、花生凝集素（PNA）、大豆凝集素（SBA）、荆豆凝集素I（UEA-I）、双花扁豆凝集素（DBA）和小麦胚凝集素（WGA）。在1日龄时，除WGA外的6种凝集素标记了麝香腺细胞。WGA在3日龄时开始标记。直到7日龄，凝集素仅与麝香腺细胞的细胞质结合。然而，在12日龄时，PNA和UEA-1均等地标记了细胞膜，RCA I在21日龄时标记了细胞膜。
