Plasma-protein production by rat hepatoma cells in culture, their variants and revertants.

A series of subclones of the H4II line of the Reuber H35 rat hepatoma produce substantial amounts of three plasma proteins, transferrin, alpha 1-antitrypsin and fibrinogen. Immunocytochemical staining demonstrated that each of these proteins is synthesized by essentially every cell of these cell populations. Cells of dedifferentiated variant clones either… (More)
