1. The presence and partial characterization of immunoreactive ANP (irANP) in eggs were investigated using high performance liquid chromatography (HPLC), immunohistochemistry and Northern-blot hybridization in mammalian and nonmammalian vertebrates. 2. Serial dilution curves of egg extracts from frogs and freshwater teleostean fishes (silver crusian carp and loach) were parallel to the standard curve of atriopeptin III. Rat oocytes also contained irANP (25-30 pg/egg). 3. The HPLC profile of irANP showed two main peaks corresponding to low and high molecular weight of irANP. 4. ANP mRNA was detected in the fish eggs. With immunohistochemical analysis of the rat ovarian follicles, this ANP-like material was localized mainly at the oocytes. 5. We, therefore, suggest that the vertebrate oocytes synthesize ANP and that the presence of ANP in the oocytes may be linked with the cell differentiation.
