Patient-Derived Xenografts: Bridging Clinical and Preclinical Research
Patient-Derived Xenografts (PDXs) are key in linking clinical and preclinical research, especially for pediatric brain tumors. They help us understand human cancers better than old cell lines do. This is because they are made from real patient tumors.
Establishing PDX Models
To make PDX models, doctors take tumor samples from patients. Then, they put these samples into mice without strong immune systems. This lets the tumors grow like they would in a real body.
These models keep the same traits as the original tumors. This makes them very useful for research.
Advantages of PDX Models in Pediatric Brain Tumor Research
PDX models are great for studying pediatric brain tumors. They let us see how different treatments work on each patient’s tumor. This helps make treatments more precise.
These models also help us understand why some treatments don’t work and how tumors grow stronger. This is key to finding better treatments.
| Feature | Conventional Cell Lines | PDX Models |
|---|---|---|
| Genetic Fidelity | Low | High |
| Tumor Microenvironment | Absent | Present |
| Clinical Relevance | Limited | High |
| Personalized Responses | No | Yes |
In conclusion, PDX models are vital for studying pediatric brain tumors. They give us specific insights and help with personalized medicine. This makes them crucial for improving cancer research.
Orthotopic Implantation: Mimicking the Tumor Microenvironment
Orthotopic implantation is key in studying pediatric brain tumors. It makes a real-life copy of the tumor’s area. Unlike other methods, it puts human tumor cells right into the mouse brain. This makes the study more like what happens in real life. Mouse Models of Pediatric Brain Tumors Reviewed
