Abstract
A cell line (JINET) which has a limited life-time in culture was established from a cynomolgus monkey kidney tissue. JINET cells lost their rapidly growing potentials at around the 40th passage level. The cell line has been maintained over 3 years by recovering cells from stocks frozen at young generations when the cells lost the rapidly growing potentials at each series of serial cultivations.
The cell line showed a high susceptibility to wide varieties of viruses almost comparable to that of primary cynomolgus monkey kidney cell cultures. Possible availability of this cell line as a substitute for primary monkey kidney cell cultures in virus researches is discussed.
