Animal cell proliferation promoter, medium for animal cell culture and animal cell culture device

摘要

An object of the present invention is to provide a novel animal cell proliferation promoter. Specifically, the culture supernatant of the embryonic membrane of an avian or reptile egg is used as an animal cell proliferation promoter. For example, by adding a cell proliferation agent containing a culture supernatant of the embryonic membrane of an avian or reptile egg as an active ingredient to an animal cell culture medium. It can promote the proliferation of animal cells.
