title: A note on the transformation of the dbrB carcionoma.
abstract: A heterofore strain-specific mammary carcinoma of the mouse was found to have acquired altered characteristics. The dbrB transplantable tumor originated in a DBA mouse as a spontaneous carcinoma in 1918. It was not until recently, when this tumor was transferred from mice to storage in the frozen state, that a marked transformation occurred both in vivo and in vitro. Certain morphologic differences were also noted.
