title: Stability of characters of mammary tumors in BALB/cfRIII mice.
abstract: The biological and morphological characteristics of mammary tumors in BALB/c mice infected with RIII mammary tumor virus (MTV) by foster nursing have substantially kept stable and unchanged after 20 years, 53 inbred generations and transfer of the strain from Perugia to Pisa. This suggests that the causal MTV keeps unaltered in time its biological properties.
