Abstract
The nature of the ovarian factor(s) stimulating biosyntheses in the ma in nidamental glands of Sepia officinalis L. was investigated using ra dioimmunoassay (RIA) and in vitro bioassay. RIA revealed the occurrenc e of progesterone in the follicles and hemolymph of maturing and matur e females. We observed a dose-dependent stimulation by progesterone of the incorporation of [C-14] labelleds D-glucose in polysaccharides of nidamental cells in suspension. These results show that the ovary is one of the organs involved in the regulation of the activity of the ma in nidamental glands.
