«Mothers and daughters: How starfish
egg cells eliminate crucial structures to ensure the embryo will be viable.»
The first complete, real - time recording of
an egg cell eliminating its centrioles shows the starfish egg cell handles mature «mother» centrioles (green) differently from immature «daughter» centrioles (purple).

So in animals, before an
egg cell is fertilised by a sperm, its centrioles are
eliminated, ensuring that the resulting embryo receives only the sperm's centrioles.
To investigate how the
egg cell manages to rid itself of such a resilient structure, Joana Pinto, a PhD student in the Lénárt lab, developed fluorescent tags for mother and daughter centrioles in a starfish
egg cell and recorded the entire process of
eliminating them.
