Area of Science:

  • Cardiovascular Research
  • Biomedical Engineering
  • Cell Biology

Background:

  • Cardiac cells respond to mechanical stress, influencing heart development and function.
  • Existing cell culture methods inadequately mimic the physical loading of the native heart.
  • There is a need for in vitro models that replicate physiological and pathological cardiac mechanical loading.

Purpose of the Study:

  • To develop a microfluidic cardiac cell culture model (μCCCM) for physiologically relevant in vitro hemodynamic stimulation of cardiomyocytes.
  • To create a system that couples cardiomyocyte structure and function with fluid-induced loading.
  • To replicate various loading conditions experienced in the heart, including normal and pathological states.

Main Methods:

  • Designed and fabricated a microfluidic cardiac cell culture chamber (1 cm diameter) on a flexible silicone membrane.

  • Integrated the chamber with a pump, pulsatile valve, and adjustable resistance for hemodynamic control.
  • Characterized fluid flow, pressure, and stretch generated at various frequencies to mimic cardiac conditions.

    • Main Results:

    • The μCCCM successfully replicates diverse hemodynamic loading conditions.
    • Proof-of-concept studies demonstrated the successful culture of H9c2 cardiomyoblast cells.
    • An in vivo-like phenotype was established within the developed microfluidic system.

    Conclusions:

    • The developed μCCCM provides a physiologically relevant platform for studying cardiac cells under mechanical stress.
    • This model enables novel in vitro investigations into cardiac function and disease.
    • The system facilitates the replication of in vivo-like cellular responses to hemodynamic forces.
