Frequently Asked Questions
Why use tumor spheroids for cancer research?
Tumor spheroids develop oxygen and nutrient gradients similar to solid tumors, including a hypoxic core. This allows researchers to evaluate how well therapeutic agents penetrate into the tumor and perform under realistic conditions that cannot be replicated in flat cell cultures.
Can 3D spheroids be used for drug screening?
Yes, 3D tumor spheroids created with 3D Petri Dish® micro-molds are widely used for high-throughput drug screening. The uniform size and reproducibility of the spheroids enables reliable dose-response measurements and comparison across experimental conditions.
Why are 3D microtissues better than traditional 2D cell cultures?
3D microtissues formed using 3D Petri Dish® micro-molds better recapitulate the complex cell-cell interactions, extracellular matrix organization, and signaling gradients found in living tissues. This leads to more physiologically relevant results compared to growing cells on flat plastic surfaces, where cells often behave differently than they do in the body.
