Uterine Gland Microstructure in the Pregnant and the Non-pregnant Lesser Galago (Galago senegalensis)

The histology and the ultrastructure of the uterine glands of the lesser bushbaby (Galago senegalensis) were studied in six specimens (5 pregnant and one non pregnant) which were fixed partly with bouin's fixative and part with 2.5% glutaraldehyde in 0.1 M cacodylate buffer. An overview of the...
