What is not utilized to culture viruses?

Explanation:

Cell culture is the process by which cells, whether prokaryotic or eukaryotic cells, can be grown under controlled conditions. In practice, the term "cell culture" is normally used in reference to the culture of cells isolated from multicellular eukaryotes, especially animal cells. The historical and methodological development of cell culture is intimately linked to the cultivar peptides of tissue culture and organ culture.

Animal cell culture began to be a routine laboratory technique during the 50,1 years but the concept of keeping living cell lines separate from the tissue of origin was discovered in the 19th century.
