In this video, we demonstrate the procedure to isolate and culture pericytes from bovine brain capillaries without endothelial cell contamination.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Seeding and Culturing of Bovine Capillaries Day 0: Mix 0.7 mL of collagen IV stock with 6.3 mL of PBS. Add the solution to a T75-flask and leave the flask for 2 h at room temperature (RT) or leave it overnight at 4 °C. Remove the collagen solution from the flask and wash three times …
Representative Results
Figure 1: Culturing of capillaries and isolation of pericytes. Capillaries have been isolated from fresh bovine brain and seeded in culture flasks on day 0. Outgrowth from the bovine brain capillaries and the following isolation of pericytes were followed over days with a light microscope. Day 4a shows the endothelial cell growth prior to treatment with trypsin to remove endothelial cells an…
