Cell-Cell Adhesion

JPK CellHesion - How it Works

A single living cell is chemically bound to the cantilever sensor (eg with a fibronectin coating) under optical control.

CellHesion In a Microscope

The cell is brought into contact with the binding target on the substrate using a defined force. The binding target could be a molecular layer, implant surface, single cell or confluent monolayer. The substrate can be a slide, coverslip or Petri dish.

Measure cellular interaction

After a specified length of time, the cantilever is retracted vertically (on the z-axis) using a piezo actuator. This separates the cell from the substrate cell.

Cellular interaction analysis

If there is adhesion, the cell resists the effort to remove it. This bends the cantilever, which is measured by a detector.

In physical terms, the cantilever is a leaf spring, so the adhesive force and energy can be calculated by measuring the bending.

This enables you to identify single-molecule binding events that contribute to the adhesion. By repeating the test with various cells, targets and conditions you can collect statistically relevant information.

Cell-Substrate Adhesion

The force vs. distance curve, enables you to calculate:

  • Single molecule events
  • “Work of removal”
  • Tether formation
  • Maximum adhesion force
  • Viscoelastic parameters
