In this video, we demonstrate the isolation of aortic valve interstitial cells from the heart of an adult mouse using a two-step collagenase procedure and their subsequent culture in low volume of growth media.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Preparation Before Valve Cell Isolation from Adult Mice Clean and sterilize all the surgical instruments shown in Figure 1A by using 70% v/v ethanol and subsequently autoclaving them for 30 min. Clean the surgical workspace with 70% ethanol. Add 500 µL of penicillin-streptomycin…
Representative Results
Figure 1: Description of valve dissection. (A) Representative image of all the surgical instruments needed for the dissection, scissors 2 is needed to open the skin of the mouse and scissors 3 to open the chest. Tweezers 5 and 6 are needed to hold the skin and open the chest. (B) …
