简介：
Overview
This article presents a protocol for ultrasound-guided injection of neuroblastoma and Ewing's sarcoma cells into murine models. This technique aims to establish reliable preclinical cancer models that reflect the native tumor microenvironment.
Key Study Components
Area of Science
- Neuroscience
- Oncology
- Preclinical Research
Background
- Patient-derived tumor cells provide a more accurate model for studying cancer.
- Orthotopic xenografts are essential for understanding tumor behavior in a native context.
- Ultrasound guidance allows for precise injection without invasive surgery.
- This method can enhance the reliability of preclinical studies.
Purpose of Study
- To create biologically relevant cancer models for research.
- To investigate tumor evolution and therapeutic responses.
- To facilitate drug discovery through improved preclinical models.
Methods Used
- Ultrasound-guided injection of neuroblastoma cells.
- Injection into the murine adrenal gland.
- Use of patient-derived tumor cells.
- Non-invasive technique to minimize recovery time.
Main Results
- Successful establishment of orthotopic xenografts.
- Demonstrated efficiency and reliability of the method.
- Provided insights into tumor behavior in a native microenvironment.
- Facilitated further studies on therapeutic responses and metastasis.
Conclusions
- The ultrasound-guided injection method is effective for cancer research.
- Patient-derived models improve the relevance of preclinical studies.
- This technique can significantly aid in drug discovery efforts.
