What are 3D spheroids?
3D spheroids are clusters of cells that mimic the architecture and functionality of tumors in vivo.
Why is T-cell cytotoxicity important?
T-cell cytotoxicity is crucial for the effectiveness of cancer immunotherapies, as it determines how well immune cells can eliminate tumor cells.
What is the advantage of using a scaffold-free model?
Scaffold-free models simplify the experimental process by eliminating the need for transferring spheroids, reducing potential damage and variability.
How are spheroids generated in this study?
Spheroids are generated by adding molten agarose into a microwell mold, allowing them to solidify and form individual spheroids.
What is the significance of using a collagen matrix?
Embedding spheroids in a collagen matrix provides a more physiologically relevant environment for studying cell behavior.
Who demonstrated the procedure in this study?
The procedure was demonstrated by Apsra Nasir, a PhD student from the department.
