Design and Applications of Cell-Selective Surfaces and Interfaces

Area of Science:

• Biomaterials Science
• Tissue Engineering
• Cell Biology

Background:

• Undesired cell accumulation and behavior impede natural tissue healing, causing immune responses, restenosis, and fibrosis.
• Biomaterials offer potential solutions by creating specific environments for cellular interactions.
• Cell-selective interfaces are crucial for directing cellular behavior during regeneration.

Purpose of the Study:

• To review the significance of cell-selective surfaces and interfaces in biomaterials for tissue regeneration.
• To explore the various cues that enable cell selectivity in biomaterial design.
• To highlight the practical applications of cell-selective biomaterials in regenerative medicine.

Main Methods:

• Review of existing literature on biomaterials, cell-selective surfaces, and tissue regeneration.
• Analysis of chemical, biological, physical, and physiological cues influencing cell behavior on biomaterials.
• Categorization of applications in endothelialization, nerve regeneration, and stem cell capture.

Main Results:

• Cell-selective biomaterials leverage chemical (peptides, antibodies), physical (topography, elasticity), and physiological (cell-cell, cell-cytokine interactions) cues.
• These cues effectively modulate cell behavior, promoting desired cellular responses.
• Demonstrated efficacy in promoting endothelialization, nerve regeneration, and stem cell capture.

Conclusions:

• Cell-selective biomaterials are vital for directing cellular activity towards successful tissue regeneration.
• The strategic design of biomaterial surfaces with specific cues can restore tissue structure and function.
• These materials hold significant promise for diverse regenerative medicine applications.
