two breast cancer cells dividingEstrogen supplements are often required in breast cancer xenograft studies, but can induce a range of adverse effects on immunodeficient mouse models. Failure to control for these strain-dependent effects can seriously impact the reproducibility of preclinical research.

In this webinar, we will explore the impacts of external estrogen supplements on various strains of mice used as breast cancer xenograft models in preclinical research. Topics will include:
  • Why external estrogen supplements are necessary in breast cancer models.

  • What kinds of adverse, estrogen-related effects are observed in mouse models.

  • How to control for strain-dependent variations in these effects.
