Frequently Asked Questions
How do 3D cardiac microtissues improve heart research?
3D cardiac microtissues enable the study of contractile function, calcium handling, and electrophysiological properties in a format that closely mimics native heart tissue. This is critical for accurate assessment of drug effects and disease modeling.
What products are used for cardiac research?
Microtissues offers several mold formats suitable for cardiac research, including the 12-256 Small Spheroids and 24-35 Large Spheroids configurations, which allow researchers to optimize microtissue size for their specific cardiac applications.
Why are 3D microtissues better than traditional 2D cell cultures?
3D microtissues formed using 3D Petri Dish&ref; 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.
