Abstract
Disclosed is a method for the culture of higher eukaryotic cells which are dependent for survival on an exogenous factor. The method involves co-culturing the factor-dependent cells with an immortalized eukaryotic cell that has been engineered to secrete the requisite factor. Also disclosed is a cell line of non-stromal cell origin which secretes interleukin-7.
