hPBMC/HSC Humanized Models

hPBMC Humanized Models

  • Established models for immune-checkpoint inhibitor and bi-specific antibody candidates in a human-resembling immune system.
  • Annotation for both immune cells (phenotyping, biomarker, functions) and tumor cells (expression, mutation, etc.)
  • Different PBMC delivery systems (systemic injection or co-inoculation with tumor)

HSC Humanized Models

  • Available humanized models from CIEA combine with WuXi PDX/CDX models.
  • Customizable with human cytokine transgenic mice (GM-CSF/hIL-3 or hIL-2) to improve the reconstitution of myeloid lineage.
