Abstract
Summary
Certain tissue cells, grown in vitro on media containing serum from stressed chickens, produce quantities of lipid deposited in droplets within their cytoplasm. Serum from non-stressed animals does not elicit this phenomenon. Being associated with a period of active proliferation, it cannot be said to be a degenerative process. Evidently it is not related to increased lipid content of the serum. The stress factor, if such there be, is more easily elicitable during physiological youth of the experimental animal. It is suggested that the phenomenon is humoral stimulated and may be a manifestation, in vitro of elevated circulating stress hormones in vivo.
