The ability of an oocyte to develop into a viable embryo depends on the accumulation of specific maternal information and molecules. Oocyte growth, particularly in oviparous species, is characterized by the intense deposition of products; e.g. RNAs, proteins (including growth and transcription factors), lipids, vitamins, and hormones. The deposit and storage occur in teleost fish species in a physiologically arrested cell at the G2/M border in first meiotic prophase (see Chapter 1).Whereas the nucleus remains in the diplotene stage, maternal RNAs are produced endogenously by the oocyte (see Chapters 3 and 6).
