Area of Science:

  • Biomedical Engineering
  • Cell Biology
  • Physiology

Background:

  • Dynamic stresses in living tissues generate interstitial flows through the extracellular matrix.
  • Interstitial flows play vital roles in tissue maintenance and pathobiology, previously underestimated.
  • These flows are essential for nutrient transport within tissues.

Purpose of the Study:

  • To present evidence on the diverse effects of interstitial flow on cell biology.
  • To explore the roles of interstitial flow in various physiological and pathological processes.
  • To discuss the mechanisms by which interstitial flow influences tissue regulation.

Main Methods:

  • Review and synthesis of existing evidence on interstitial flow.
  • Analysis of studies investigating cellular responses to fluid flow.

  • Examination of proposed mechanisms of morphoregulation induced by interstitial flow.
  • Main Results:

    • Interstitial flow impacts embryonic development, tissue morphogenesis, and remodeling.
    • It plays a role in inflammation, lymphedema, tumor biology, and immune cell trafficking.
    • Mechanisms include direct shear stress, matrix-cell transduction, and autologous gradient formation.

    Conclusions:

    • Interstitial flow is a significant factor in cell biology with broad implications.
    • Understanding these flows is critical for addressing various diseases and developmental processes.
    • Further research into the mechanisms of interstitial flow is warranted.
