Abstract
The present invention aim at providing a novel animal cell growth promoter. Specifically, a culture supernatant of an embryonic membrane derived from an avian or reptilian fertilized egg is use as an animal cell growth promoter. For example, by adding, to an animal cell culture medium, an animal cell growth promoter comprising, as an active ingredient, a culture supernatant of an embryonic membrane derived from an avian or reptilian fertilized egg, the animal cell growth can be promoted.
