What is the significance of using 3D cultures?
3D cultures provide a more accurate representation of tissue architecture and cell behavior compared to traditional 2D cultures.
How does the perfusion bioreactor system work?
The perfusion bioreactor system continuously supplies nutrients and oxygen to the cell cultures, mimicking physiological conditions.
What parameters can be evaluated in the surrogates?
Parameters such as cell density, viability, and response to therapeutics can be assessed in the surrogates.
Can this method be adapted for other types of cancer?
Yes, the method can be modified to study different types of cancer by altering the cellular composition and conditions.
What are the advantages of using histologic sections?
Histologic sections allow for detailed examination of cellular organization and morphology within the surrogates.
Is this method suitable for high-throughput screening?
The method can be adapted for high-throughput screening of therapeutic candidates due to its reproducibility and scalability.
