## Abstract Addition of (Arg) vasopressin to quiescent cultures of Swiss 3T3 cells rapidly stimulates an ouabainβsensitive ^86^Rb uptake. In contrast the hormone has no significant effect on the rate of efflux of this cation from preloaded cells. The stimulation of ^86^Rb uptake is cycloheximideβin

The growth of an epithelial canine kidney line (MDCK) was reversibly arrested by gradually lowering t h e serum concentration in the medium over a 3-day period. The cells were demonstrably quiescent by autoradiography after an additional 24 hours in serum-free media. Addition of fresh serum produced
## Abstract Recently, we have found that an increase in the intracellular level of cAMP acts as a mitogenic signal for Swiss 3T3 cells (Rozengurt et al., Proc. Natl. Acad. Sci. USA, 78:4392, 1981). The results presented in this paper demonstrate that addition of cAMPβelevating agents to confluent a
