Vero cells are especially useful for:

Vero cells are particularly valuable for vaccine production and virology because deletion of interferon alpha/beta genes prevents establishment of antiviral state normally triggered by viral RNA sensing via RIG-I and MDA5 activating IRF3. Consequently viruses replicate to high titers enabling efficient bulk production under Good Manufacturing Practice. Poliovirus inactivated polio vaccine, rabies vaccine, Japanese encephalitis vaccine, and rotavirus vaccine are produced in Vero microcarrier cultures. Regulatory agencies accept Vero because extensive documentation demonstrates absence of tumori

Animal Tissue Culture 3

Vero cells originate from:

Vero cell line originates from kidney epithelial tissue excised from adult African green monkey Chlorocebus aethiops, formerly Cercopithecus aethiops, at Chiba University Japan in 1962 by Yasumura and Kawakita. Designation Vero derived from Esperanto phrase Verda Reno meaning green kidney. Cells exhibit epithelial-like cobblestone morphology, anchorage dependence, contact inhibition, and were initially diploid but later became aneuploid after continuous passage. Critical molecular feature is homozygous deletion of approximately 9 megabase region on chromosome 12 encoding type I interferon gene
