CAR-T Cell Therapies Platform

Chimeric antigen receptor (CAR)-T cell therapy represents a major advancement in personalized cancer treatment. This therapy has shown remarkable results with hematological malignancies (including anti-CD19 CAR-T therapy against B cell malignancies).  To help accelerate research in this field, we provide a comprehensive platform of in vitro services and in vivo animal models for supporting project teams focused on the discovery of CAR-T cell therapies.

In vivo Efficacy

In vivo anti-tumor
• Endpoints: Tumor volume measurement for subcutaneous models; bioluminescence imaging for systemic models and orthotopic models; survival analysis
• Clinical Observation: Food consumption, body weight, behavior and morphology, necropsy at the endpoint
CAR-T viability and biodistribution• In vivo proliferation, survival, and long-term persistence of CAR-T cells
• Tumor or tissue distribution and infiltration of CAR T cells
• T cell phenotype analysis (Memory and effector T cells, Tregs)
Toxicity evaluation
• Cytokine release analysis
• Single dose toxicity
• Potential tumorigenicity of CAR-T cells
  • Tumor volume measurements (for subcutaneous models)
  • Bioluminescence imaging (for systemic and orthotopic models)
  • Survival analysis
  • Clinical observations (including necropsy at endpoint)
  • Infiltration of CAR-T cells in tumor and tissue
  • Proliferation, survival, and long-term persistence of CAR-T cells
  • T cell phenotype analysis (e.g., memory and effector T cells, Tregs)
  • Toxicity assessment (including single-dose toxicity and cytokine release)
