Background
- Metastasis research requires advanced imaging techniques for real-time monitoring.
- Current methods often lack the sensitivity to track single cancer cells or early-stage metastasis.
- Visualizing tumor progression and drug response in vivo is crucial for therapeutic development.
Purpose Of The Study
- To develop a novel imaging method for detecting and quantifying cancer metastasis in vivo.
- To utilize green fluorescent protein (GFP) for real-time visualization of tumor cells and metastatic spread.
- To establish a platform for studying tumor progression, metastasis, and evaluating drug efficacy.
Main Methods
- Genetically engineered mice with tumor cells expressing green fluorescent protein (GFP).
- Introduction of the GFP gene into human and rodent cancer cell lines for stable expression post-transplantation.
- Development of in vivo transduction techniques for GFP expression in tumors.
- Quantitative transcutaneous whole-body fluorescence imaging for external visualization of GFP-expressing tumors and metastases.
- Application of GFP technology for imaging and quantifying angiogenesis.
Main Results
- Successful imaging of metastases in mice using GFP-expressing tumor cells, both in situ and externally.
- Demonstrated real-time studies of tumor progression, metastasis, and drug-response evaluations.
- Established GFP-expressing human and rodent cancer cell lines that stably express GFP after transplantation.
- Visualized GFP-expressing tumors in multiple organs including colon, prostate, breast, brain, liver, lymph nodes, lung, pancreas, and bone.
- Enabled imaging and quantification of angiogenesis in real-time.
Conclusions
- Green fluorescent protein (GFP) imaging provides a powerful tool for studying cancer metastasis in mice.
- This technology facilitates real-time monitoring of tumor progression, metastatic spread, and therapeutic responses.
