Abstract

A method of culturing avian cells in a medium with a pH value of 7.8 or above, whereby avian cells can be subcultured stably for long. Since avian cells have been incapable of subculture heretofore, it has been impossible to effect in vitro cell or gene manipulation therewith. Now that such a manipulation becomes possible by the invention method, the way is opened for the industrial utilization of avian cells in the creation of transgenic birds and the production of vaccines.
