## Abstract It has been shown that hamster cells transformed after treatment with the chemical carcinogen dimethylnitrosamine (DMNA) in which the transformed state has become a hereditary cellular property, can, like cells transformed by polyoma virus, produce a high frequency of variants with a re

## Abstract Variants from polyoma virus transformed cells in which reversion was not associated with a loss of the virus genome have been studied at 3 and 33 weeks after clone isolation. The variants reβreverted during this in vitro cultivation for properties which were initially suppressed. This r
## Abstract The stability of the reverted state has been analysed in revertants from polyomavirusβtransformed cells in which reversion was not associated with a loss of the virus genome. The regaining of two transformed properties, the ability to form colonies at high temperature (41Β° C) and in sof
## Abstract Cells transformed after treatment with the chemical carcinogen dimethylnitrosamine (DMNA) inoculated into animals, can produce tumors containing variants with a reversion of in vitro properties of transformed cells. In contrast to variants from tumors produced by polyomaβtransformed cel
## Abstract The changes in chromosome constitution that occur during induction of reversion in transformed cells have been studied. The culture of transformed cells at low cell density without a feeder layer, which induces reversion, also induced a change in chromosome number from diploid to aneupl
The method for measuring the surface tension of a fluid drop or bubble from the amount of flattening it undergoes when resting on a surface, has been used chiefly in the case of mercury o r gases. In these substances the difference in density between medium and drop is great enough to cause sufficie
