This video describes the isolation of antral oocytes from freshly harvested mouse ovaries. These antral oocytes can be used for further characterization and developmental studies.

Protocol

All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Animals Maintain adult 3- to 6-week-old female mice in a room with controlled temperature and humidity (with phases of 12L:12D and fed ad libitum). Inject mice intraperitoneally with 2.5 IU of Pregnant mare serum gonadotropin (PMSG) to stimulate follicular growth by mimicking the effects of folli…
