What is the significance of ECM in cell culture?
ECM provides structural and biochemical support to cells, influencing their behavior and function.
How does the absence of chemical crosslinking benefit the scaffolds?
It maintains the natural properties of the ECM, promoting better cell interaction and function.
What applications can these ECM-derived materials have?
They can be used in 3D in vitro cell culture models and as bioscaffolds for tissue regeneration.
Can the geometries of the scaffolds be customized?
Yes, the method allows for the fabrication of scaffolds with tunable geometries.
What are the advantages of using lyophilized ECM?
Lyophilization preserves the ECM structure and allows for easy handling and storage.
How does cryomilling contribute to the process?
Cryomilling produces a fine powder of ECM, which is essential for creating uniform scaffolds.
