title: [Antimitotic factors - chalones].
abstract: In order test the effect of liver chalone the tested substance was injected into the amniotic sac of a chicken embryo. As the results suggest, it proved possible to isolate from the liver a substance capable of affecting profoundly the proliferative activity of embryonic liver tissue. The substance was tissue-specific, species-nonspecific, and its action on the tissue was seen as reversible.
