Ultrastructure of oocytes and follicular cells during vitellogenesis of Eriocheir sinensis;

The expressions of bFGF gene in goat ovarian follicle, cumulus-oocyte complexes (Caprane) (COCs), granulosa cells(GCs) and theca follicular cells were observed, respectively.

34×10 -2 mol/L ferric ion tothe culture liquid of follicle cells and pituitary cells,it observed theeffects of 3 levels of ferric ion on excretion of oestrogen and progesterone in vitro follicle cells and its mixed with pituitary cells.

Research on cryopreservation of bovine follicular oocytes;

Studies on Cryoperservation and in Vitro Culture of Porcine Follicular Oocytes;

In order to gain the follicular oocytes which was high quality,and improve the frequency of in vitro production of the goat s embryos,the dissection method and the aspiration method were applied to collect the follicular oocytes of the goats,and the available oocytes were used to be in vitro maturation.
