Background:

  • Poly(lactic-glycolic acid) (PLGA) is a biocompatible material widely used for cell scaffolds.
  • PLGA's inherent hydrophobic and neutral surface properties limit its efficacy in cell adhesion and tissue integration.
  • Existing strategies involve coating PLGA scaffolds with polymer, extracellular matrix (ECM) mimics, or organic materials to overcome these limitations.

Purpose of the Study:

  • To review surface-modified materials, methods, and applications for PLGA-based cell scaffolds.
  • To highlight how surface modifications improve cell adhesion and tissue adaptation.
  • To provide guidance for future PLGA surface modification strategies.

Main Methods:

  • Review of literature on PLGA surface modification techniques.
  • Analysis of various coating materials (polymers, ECM mimics, organic materials).
  • Examination of physical and chemical modification methods.

Main Results:

  • Surface modification significantly enhances cell adhesion to PLGA scaffolds.
  • Coating strategies can modulate cell behavior and function, improving tissue adaptation.
  • Multiple material coatings can impart diverse functionalities to PLGA scaffolds simultaneously.

Conclusions:

  • Surface modification is crucial for optimizing PLGA scaffold performance in tissue engineering.
  • Diverse coating materials and methods offer versatile solutions for enhancing PLGA scaffolds.
  • This review provides a comprehensive overview to guide the development of advanced PLGA-based cell scaffolds.
