Test animals / tissue source
- Details on test animals or tissues and environmental conditions:
- The fertile Lohmann Brown extra hen eggs (Brinkschulte Josef GmbH & Co.KG, 48308 Senden) were incubated in an incubator with an automatic rotating device (e.g. Ehret GmbH), optimum temperature : 37.5 °C, relative humidity 63%.
After 7 days of incubation, all eggs were candled in order to discard those that were defect and to mark the air bubble. The eggs were replaced into the incubator with the large end upward but not rotated, thus ensuring accessibility to the CAM region.
At day 8 of incubation the sections marked for the air bubble were sawed out of the shell. The inner membrane was moistened with NaCl 0.9 % and carefully removed with forceps. Only eggs with normally developed embryos and blood vessel systems were used for testing.
