What is the significance of using a chicken embryo model?
The chicken embryo model provides a living system to study tumor behavior and drug effects in a controlled environment.
How do mesenchymal cells support multiple myeloma cells?
Mesenchymal cells provide essential signals and a supportive extracellular matrix that promote the survival and proliferation of myeloma cells.
What are the advantages of 3D models in cancer research?
3D models better mimic the tumor microenvironment, allowing for more accurate assessments of drug efficacy and tumor behavior.
What types of cancer drugs were tested in this study?
The study focuses on anti-cancer drugs that target tumor growth and invasion, although specific drugs are not detailed in the summary.
How can this research impact future cancer therapies?
