Abstract Transforming growth factor beta 1 (1 ng/ml) caused death of serum-free mouse embryo cells cultured in a medium consisting of a 1:1 mixture of Dulbecco's Modified Eagle's medium and Ham's F12 medium supplemented with fibronectin, insulin, transferrin, epidermal growth factor, and high density lipoprotein. Cell death occurred in the presence of polyunsaturated fatty acids including linoleic acid in the absence of selenium. The death could be reversed by adding α-tocopherol to the culture indicating a mechanism involving fatty acid peroxidation. Butylated hydroxytoluene was a poor suppressor of cell death in contrast to α-tocopherol. High density lipoprotein and fatty acid-free albumin also suppressed cell death at the level of 20 μg/ml and 1 mg/ml, respectively. Transforming growth factor β1 also caused a low rate of cell growth after heat treatment of the cells at 45°C.
