ABSTRACT
The Mustelus uterus is unusual in having, as well as the thin apical cells, a subpopulation of rather globular cells which express large amounts of N-acetyl glucosamine oligomers (Fig. 15.12F) and cx2,3-linked sialic acid. Their sporadic nature on the surface of the uterus made their function unclear although the richly glycosylated, vesicular contents suggest a secretory function similar to that of the goblet cell, and they might be the source of the globular deposits occasionally seen lying against the undersurface of the egg envelope.
