Notes

The primary interaction of cultured Tetrahymena cells with a hormone (insulin in the present case) gives rise to hormonal imprinting, which accounts for a considerable increase in the latter hormone binding capacity of the cells. Mixed culturing of imprinted and not imprinted (virgin) cells results in transmission to the latter of the information mediated by imprinting and thereby in a considerable increase in hormone binding over that of pure hormone-preexposed cell cultures. The material substrate of intercellular information transmission is a cellular secretion which appears in the nutrient medium, and is increasingly released in presence of not imprinted (virgin) cells in the mixed culture.
