Assessed angiogenic characteristics, chemotherapy sensitivity, and malignant potential.

Compared findings with standard 3D Matrigel culture and in vivo experiments.

Main Results:

3D culture within the biomimetic system dramatically altered tumor cell angiogenic characteristics, closely mirroring in vivo tumors.
Cells cultured in the model showed reduced sensitivity to chemotherapy.
The model yielded tumors with enhanced malignant potential.
Broad relevance was confirmed across different tumor cell lines.

Conclusions:

The developed biomimetic 3D model accurately replicates tumor microenvironments.
This model offers a powerful tool for studying tumor malignancy in vitro and in vivo.
It provides a broadly applicable system for cancer research and drug development.
