• To explore the potential of synthetic polymers in controlling cell behavior for biomedical applications.

Main Methods:

• Synthesis and characterization of hydrophilic polymers, focusing on hydroxyethyl methacrylate (HEMA).
• Evaluation of bioactive protein adsorption onto polymer surfaces.
• Assessment of cell adhesion and functional responses to different polymer chemistries.
• Analysis of the impact of hydrophilic/hydrophobic balance and charged functional groups on cell interactions.

Main Results:

• Hydrophilic polymers, particularly HEMA-based ones, effectively model cell-polymer interactions.
• Polymer properties like hydrophilicity/hydrophobicity and charged groups significantly modulate protein adsorption and cell adhesion.
• A copolymer of HEMA with sodium methacrylate demonstrated reduced macrophage recognition, indicating potential for implantology.
• Synthetic polymers can actively participate in controlling cell function, analogous to natural extracellular matrix components.

Conclusions:

• Hydrophilic polymers are valuable tools for dissecting the mechanisms of cell-biomaterial interactions.
• Tailoring polymer molecular design allows for precise control over protein adsorption, cell adhesion, and cell function.
• These findings support the development of novel synthetic biomaterials for diverse biomedical applications, including clinical implantology.
