- Accelerating Drug Discovery
MCF7 (Luc) is a cell line derived from a breast cancer patient that is widely used in xenograft mouse models to investigate the growth and progression of breast cancer.
HCT116 and MC38 are colon cancer cell lines used in colon cancer xenograft tumor models. HCT116 is a human colorectal carcinoma cell line that has DNA mismatch repair-deficiency.
KRAS is mutated in 90% of pancreatic cancers. The Panc-1 and Panc-10.05 cell lines were derived from different patients with pancreatic adenocarcinoma and offer the ability to study different KRAS mutations.
A375 and SK-MEL-28 are melanoma cell lines that have been employed in xenograft mouse models. A375 has a BRAF V600E mutation and SK-MEL-28 has a NRAS Q61R mutation.
AML (Kg-1a) cell line has MLL and AF9 gene fusion from a patient with acute myeloid leukemia. MLL regulates gene expression, while AF9 modifies chromatin.
What are Cell-Line Xenograft (CDX) models?
Cell-line derived xenograft models aid in advancing the formulation of anti-cancer therapies, as they provide a platform for the exploration of cancer complexities. By using cancer cells that originated in laboratories, CDX models use implanted human tumor cells in mice with suppressed immune systems to create an environment that aids the progression and maturation of these tumor cells.
- High Reproducibility
- Large Scale Testing
- Genetic Manipulation
- Rapid Experimentation

Visualization Techniques in Xenograft Models
Tracking tumor volume in Nude mice
A549 cells carry mutations in KRAS, STK11, and CDKN2A genes that are commonly found in non-small cell lung cancer (NSCLC). Targeting KRAS mutations has become a popular approach for treating NSCLC, as these mutations are present in approximately 25% of cases and are associated with a poor response to therapy.
Localizing SNU-638 cells in immunocompromised mice using GFP and Luciferase labeling
SNU-638 is a human gastric cancer cell line that is commonly used in xenograft mouse models for studying the growth and behavior of human gastric cancer cells. GFP labeling allows to visualize the location of the tumor and Luciferase labeling allows precise quantification of the numbers of tumor cells present throughout a treatment.
