phase-contrast microscopic image of vero cells (under green light at 100-fold magnification)
vero cells are a lineage of cells used in cell cultures. the 'vero' lineage was isolated from kidneyepithelial cells extracted from an african green monkey (chlorocebus sp.; formerly called cercopithecus aethiops, this group of monkeys has been split into several different species). the lineage was developed on 27 march 1962, by yasumura and kawakita at the chiba university in chiba, japan. the original cell line was named "vero" after an abbreviation of verdareno, which means "green kidney" in esperanto, while vero itself means "truth" in esperanto.
