What is the CAM assay?
The CAM assay is a technique used to study tumor behavior in a living embryo model, allowing for the observation of tumor-host interactions.
Why is the CAM assay advantageous?
It is simple to learn, cost-effective, and does not require ethical committee approval, making it accessible for various research applications.
What types of tumors can be studied using this method?
The CAM assay can be used to study various tumors, including sarcomas and other cancer types, using patient-derived materials.
How is the tumor material prepared for the CAM assay?
Tumor samples are cut into small pieces, digested, and processed into a single-cell suspension before being applied to the CAM.
What are the main outcomes measured in the CAM assay?
Key outcomes include tumor viability, cell proliferation, vascularization, and host tissue responses.
