Ovarian follicle structures of mice; secondary follicles (A), graaffian follicles (B) and cumulus-enclosed germinal vesicle oocytes (Mohammed AA)
Mice denuded germinal vesicle oocytes (A) and cumulus-enclosed germinal vesicle oocytes (B)
Complete and selective enucleation of denuded and cumulus-enclosed germinal vesicle oocytes; complete enucleation with removal the whole nucleus (A,B) and selective enucleation leaving the nuclear sap and nucleolus in the cytoplast (C,D).
