Vero Cell
Vero cells are lineages of cells used in cell cultures.
The Vero lineage was isolated from kidney epithelial 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 "Verda Reno", which means "green kidney" in esperanto, while "vero" itself means "truth" also in Esperanto.
Vero cells are used for many purposes, including:
- screening for the toxin of Escherichia coli, first named "Vero toxin" after this cell line, and later called "Shiga-like toxin" due to its similarity to Shiga toxin isolated from Shigella dysenteriae.
- as host cells for growing virus; for example, to measure replication in the presence or absence of a research pharmaceutical, the testing for the presence of rabies virus, or the growth of viral stocks for research purposes.
- as host cells for eukaryotic parasites, specially of the Trypanosomatids.
The Vero cell lineage is continuous and aneuploid. A continuous cell lineage can be replicated through many cycles of division and not become senescent. Aneuploidy is the characteristic of having an abnormal number of chromosomes.
Vero cells are interferon-deficient; unlike normal mammalian cells, they do not secrete type 1 interferons when infected by viruses. However, they still have the Interferon-alpha/beta receptor so they respond normally when interferon from another source is added to the culture.

Famous quotes containing the word cell:
“She that but little patience knew,
From childhood on, had now so much
A grey gull lost its fear and flew
Down to her cell and there alit,
And there endured her fingers touch
And from her fingers ate its bit.”
—William Butler Yeats (18651939)
