Cell patch seeding using thermoresponsive surfaces enhances osteoblast function and proliferation on porous hydroxyapatite scaffolds for tissue engineering applications.

Area of Science:

  • Biomaterials Science
  • Tissue Engineering
  • Cell Biology

Background:

  • Cell seeding is critical for the success of tissue-engineered constructs.
  • Traditional cell seeding methods can impact cell viability and function.
  • Developing efficient methods for cellularizing scaffolds is essential for regenerative medicine.

Purpose of the Study:

  • To evaluate a novel cell patch seeding method for generating in vitro tissue constructs.
  • To compare the efficacy of cell patch seeding versus trypsinization for cellularizing bone substitute materials.
  • To assess the impact of seeding method on osteoblast proliferation and function on porous and dense hydroxyapatite.

Main Methods:

  • Osteoblast cells were seeded onto porous and dense hydroxyapatite using a thermoresponsive poly(N-isopropylacrylamide) surface for cell patch retrieval.

  • Cellularization was achieved via cell patch transfer and a conventional trypsin method.
  • Cell proliferation, viability (Live-dead staining), and alkaline phosphatase activity were analyzed after 7 days of culture.

    • Main Results:

    • Cellularized porous hydroxyapatite (PHA) exhibited a higher relative cell growth rate compared to dense hydroxyapatite.
    • Live-dead staining confirmed the presence of viable cells within the pores of PHA.
    • The cell patch seeding method resulted in significantly higher alkaline phosphatase activity than the trypsin method, indicating enhanced cell function.

    Conclusions:

    • Cell patch seeding using thermoresponsive surfaces is a successful novel method for cellularizing scaffolds.
    • This technique preserves osteoblast cell function and promotes proliferation, particularly on porous hydroxyapatite.
    • The cell patch method offers advantages over trypsinization for generating functional in vitro tissue constructs for regenerative medicine.
