Abstract
Aim: Cell microenvironment contains a plethora of information that influences cell modulation. Indeed, the extracellular matrix plays a central role in tissue development. Reproducing the cell-extracellular matrix crosstalk able to recapitulate both physical and biochemical signals is crucial to obtain functional tissue models or regenerative strategies. Materials & methods: Here, a combined method is proposed to easily functionalize collagen surface films, tailoring morphological properties. Oxygen nonthermal plasma treatment and glyco-conjugation with chondroitin sulfate are used to modify surface properties. Results: It results in higher adhesion, proliferation and morphological organization of U87 glioblastoma cells. Conclusion: Our finding suggests new promising strategies for the development of collagen-based biomaterials, which can be employed for advanced in vitro models.
