(1) Ova, which are produced during oogenesis, are generated in gonial cells ( oogonia ) of the female's ovaries.

(2) The ultrastructure of oogenesis in the fern Osmunda cinnamomea L.

(3) The oogenesis and oocyte apoptosis of Atractomorpha sinensis Bolivar were observed by using routine histological techniques.

(4) It is obvious that the oogenesis always accompanys with the variation of the structure and the shape of the follicle cell.

(5) The oogenesis of Gambusia affinis is divided into 6 phases.

(6) Derivation of oocyte like cells from adult stem cells would benefit the study of oogenesis.

(7) In this study(Sentencedict.com ), the developmental process of the prawn oocytes was examined with light microscope and the cathepsin C activity was measured during oogenesis and final oocyte maturation.

(8) In this study, we have identified and characterized a histone H2A variant h2af1o in fish, and revealed its oocyte-specific expression pattern during oogenesis and embryogenesis.

(9) The result showed that the EM is not able to statistically affect the ovarian development and oogenesis of bumblebee queens in preoviposition period.

(10) This research can be a foundation for preparation of ZP3 polyclonal antibody and further study about the expression characteristics of ZP3 in the process of oogenesis.

(11) Compared with workers, there was only a differentiation stage in oogenesis in soldiers and no growth stage.

(12) In addition, the changes and functions of the Golgi complex in oogenesis were discussed in this paper.
