Abstract: | Summary Seven epithelial cell lines derived from kidney and 20 fibroblastic cell lines deriving from lung, heart, muscle, kidney, and skin tissue of five rhesus and six African green monkey fetuses have been established and propagated in culture. Four epithelial cell two fibroblastic cell lines resumed cell multiplication after a period of growth decline, and these lines developed cytogenetic changes and growth characteristics of cells capable of unlimited growth in vitro. Sixteen of the fibroblastic lines derived from lung, heart, muscle, or skin were characterized by a finite life consisting of a period of active cell multiplication, followed by growth decline, senescence, and cell death. Fibroblasts derived from lung appeared to have the greatest growth potential in terms of total population doublings, and fibroblastic lines from rhesus monkeys were usually capable of more doublings than similar lines from African green monkeys. All fibroblastic lines were predominantly diploid during active growth from passages 1 to 30, but several lines developed karyological changes preceding or during growth decline and senescence. All lines tested were found sensitive to a number of human viruses. All tests on these cells for microbial agents and for tumorigenicity have been negative, and the have been preserved by freezing without loss of properties. These cell lines may be useful as standardized substrates in studies requiring nonhuman primate cells. The research upon which this publication is based was performed pursuant to Contract No. NIH-69-100 with the Division of Biologics Standards of the National Institutes of Health. |
