Figure A11.

Illustration of the grafting protocol. The following sequential steps are shown: Extraction of the egg white on ED3. Opening of the egg on ED8. Grafting of the tested samples on the CAM on ED8. The cell suspension grafting is shown; a sterile white rubber ring taken from a 1.5 mL cryovial (inner diameter 8 mm) is used to prevent the leakage of the suspension. The last (right) image shows the same egg on ED12. The arrow shows a bifurcation of a blood vessel as a preferential grafting site.
