Genetically Engineered Mouse Models (GEMM) are transgenic animals in which gene knock-out and knock-in technologies have made it possible for us to more faithfully mimic the genetic and biological evolution of human cancers. GEMM studies by nature take longer to fill cohorts due to genetic mutations required for experimental animals due to more breeding required. The MP1U has 4 actively breeding models, 2 melanoma and 2 breast, available:

Syngeneic Models


While GEMMS off whole animal microenvironment for tumor studies, the MP1U has the capability to ramp up project speeds by using syngeneic tumor grafts or cell line implants. Large cohorts of animals can be studied simultaneously to meet the requirements of the project. The current models we have readily available are:


  • T11 (Breast)
  • Braf PTEN Tyr-Cre (Melanoma)
  • K14pBRCA1_B (Breast)
  • BBN (Bladder)
  • UPPL (Bladder)
  • TRIA (Melanoma)
