Egg Microinjection (image) McGill University Health Centre Caption This image shows an egg being immobilized using a holding pipette on the right, while an injection pipette carrying the solution to be injected into the egg is pushed in from the left. The egg is surrounded by a thick wall. The feeding tubes growing out from the follicle cells have to punch their way through the wall to reach the egg.
