Neonatal Mouse Ovary Isolation: A Surgical Procedure to Harvest Pair of Ovaries from Neonatal Mouse Model

Samenvatting

Source: et al. Morgan, S. Culture and Co-Culture of Mouse Ovaries and Ovarian Follicles. J. Vis. Exp. (2015).

In this video, we describe a surgical procedure to isolate ovaries from a neonatal mouse.

Protocol

All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 

1. Neonatal Ovary Dissection and Culture

1. Place 1 mL of dissection medium (dissolve 3 mg/mL BSA in Leibowitz L15 medium and filter sterilize through a 0.2 µm pore, 25 mm diameter filter) into each sterile glass embryo dish.
2. Cull neonatal mouse pups aged between postnatal day 0 and 5, culling by decapitation.
3. Grasp the skin covering the abdominal wall using a pair of fine dissection forceps and make a large incision in the skin and body wall....
