Figure 5From: Multifunctional Nanocarriers for diagnostics, drug delivery and targeted treatment across blood-brain barrier: perspectives on tracking and neuroimagingThe Xenograft and genetically engineered mouse model (GEMM). In Xenograft mouse models, cancer cells are generally injected subcutaneously into immunodeficient mice. Oncogenes in GEMM are activated and/or tumour-suppressor genes (TSGs) are inactivated somatically.Back to article page
