title: Properties of the H-4-II-E tumor cell system. I. Growth and cell proliferation kinetics of an experimental hepatoma.
abstract: Growth and cell proliferation kinetics of hepatoma H-4-II-E and its tissue culture derivative have been studied to establish the characteristics of an in vivo--in vitro solid tumor model. The H-4-II-E line, originating from the Reuber H-35 hepatoma, can be maintained and studied either in cell culture or as a transplantable solid tumor in ACI male rats. In addition it allows for the in vitro assay of cell survival following treatment of animal tumors in situ. In vivo, hepatoma H-4-II-E is rapidly growing tumor with a mean doubling time of 49-2 hr. The cell cyle time is 39-1 hr with a cell loss factor of 0-32. Retrospective examination of tumor specimens obtained during the establishment of the H-4-II-E tumor system demonstrates that both structural as well as cell population changes have occurred. The biological characteristics of the primary tumor (H-35) and an early intermediate stage (H-35tc2) are compared with H-4-II-E and the histopathological, growth and cell kinetic changes are discussed.
