Area of Science:

  • Biochemistry and Biomaterials Science
  • Protein Engineering and Drug Delivery

Background:

  • Growth factors regulate cell proliferation and differentiation, impacting healing and disease.
  • In vivo instability (short half-life, degradation) limits therapeutic efficacy.
  • Effective delivery requires carriers protecting growth factors from degradation.

Purpose of the Study:

  • Review physicochemical properties of macroions, growth factors, and their assemblies.
  • Explore potential medical applications, including wound healing and cancer therapy.
  • Highlight specific growth factors (VEGF, FGF, neurotrophins) and macroion types (synthetic, polysaccharides).

Main Methods:

  • Literature review of scientific articles on macroion-growth factor interactions.
  • Analysis of physicochemical properties: biocompatibility, binding affinity, stability, charge.
  • Focus on carrier mechanisms for protection and targeted delivery.

Main Results:

  • Macroions offer protection against heat, pH, and proteolysis.
  • Biocompatible synthetic macroions and natural polysaccharides show promise as carriers.
  • Understanding binding mechanisms is key to optimizing delivery systems.

Conclusions:

  • Macroion carriers can significantly improve growth factor stability and therapeutic delivery.
  • Applications span diabetic wound healing, tissue regeneration, and cancer therapy.
  • Further research into binding mechanisms will advance treatment for chronic wounds and neurodegenerative diseases.
