This study introduces a method to create nanostructured hydrogels for tissue engineering by incorporating Pluronic® F127. These nanostructures influence fibroblast cell morphology and spreading, offering insights into tissue regeneration.

Area of Science:

  • Biomaterials Science
  • Tissue Engineering
  • Nanotechnology

Background:

  • Hydrogel scaffolds are crucial in tissue engineering for controlling cell behavior via cell-matrix interactions.
  • Nanostructuring hydrogels offers a means to precisely guide cellular fate and tissue development.

Purpose of the Study:

  • To develop a method for nanostructuring poly(ethylene glycol)-fibrinogen (PEG-fibrinogen) hydrogels using Pluronic® F127.
  • To investigate the self-assembly of Pluronic® F127 into micelles within the hydrogel matrix.
  • To understand the relationship between hydrogel nanostructure and fibroblast cell morphology.

Main Methods:

  • Crosslinking poly(ethylene glycol)-fibrinogen (PEG-fibrinogen) with Pluronic® F127.
  • Utilizing Small-angle X-ray scattering (SAXS) and cryogenic transmission electron microscopy (cryo-TEM) to characterize nanostructures.

  • Performing time-dependent swelling and Pluronic® F127 release assays to assess micelle stability.
  • Conducting cell culture experiments with fibroblasts to evaluate 3D morphology and spreading.

    • Main Results:

    • Pluronic® F127 self-assembled into micelles within the PEG-fibrinogen hydrogel, forming nanostructures.
    • Increased Pluronic® F127 concentration led to higher micelle density and order.
    • Pluronic® F127 micelles showed transient stability, with significant release and structural changes after 4 days.
    • Fibroblast cell spreading strongly correlated with the hydrogel's mesh size, indicating structural influence on cell morphology.

    Conclusions:

    • The developed method successfully creates nanostructured hydrogels for tissue engineering applications.
    • Hydrogel nanostructure, influenced by Pluronic® F127 micelles, significantly impacts fibroblast cell morphology and spreading.
    • This research provides a quantitative understanding of how hydrogel microenvironment structure affects cell morphogenesis for tissue regeneration.
