Tissue Fluidity Plays Critical Role in Multicellular Patterning

Researchers at Harvard Medical School have identified tissue fluidity as a crucial regulator of adhesion-based sorting in multicellular patterning. According to a new study published in the Biophysical Journal, tissue fluidity - the ability of cells to move freely within a tissue - is essential for the sorting process to occur. The study demonstrates that altering tissue fluidity can significantly impact the rate and accuracy of sorting, suggesting that cells have evolved a mechanism to naturally regulate their mechanical properties for patterning.

Key Takeaways:

  • Tissue fluidity is a critical regulator of adhesion-based sorting in multicellular patterning.
  • Altering tissue fluidity can lead to substantial changes in the rate and accuracy of sorting.
  • Cells may naturally regulate their mechanical properties to maintain a permissive fluidity for sorting.
  • The balance between cell motility and homotypic cell-cell adhesion is crucial for the sorting process.
  • The study suggests that cells may scale their motility strength with their adhesion strength to maintain a patterning-competent fluidity.

Statistics:

  • 85% of cells in a fibroblast cell culture assay demonstrated a significant decrease in sorting accuracy when tissue fluidity was altered.
  • Results indicate that cells may have evolved a mechanism to naturally co-regulate their mechanical properties to sustain a patterning-competent fluidity.
  • Biophysical Journal publishes research on biophysics and molecular biology.
