Questo video descrive un metodo di microiniezione per la consegna di cellule di cancro al seno nello spazio perivitellino di embrioni di pesce zebra transgenico. Dopo l'incubazione, visualizziamo l'embrione al microscopio a fluorescenza per osservare l'invasione, la disseminazione e la metastasi delle cellule tumorali.
