Embodiments of a method for the production of human urokinase are
disclosed. Also disclosed are embodiments of a cell culture well-suited
for use with the disclosed method. The method involves culturing
urokinase-producing cells, such as immortalized human renal cells, in a
cell culture. The cell culture comprises microcarrier structures and a
tissue culture medium. The urokinase production is allowed to occur while
the cell culture remains relatively static, i.e., the cell culture is not
substantially mixed.
