Epithelial cell response to local substrate deformation (VIDEO)

Tampere University

Caption

Calcium indicator expressing epithelial cells were grown on Dispersive Red 1 (DR1)-glass substrate. The substrate deformation and topographical change was induced by generating line-like patterns to the surface with 488 nm laser light. The rise in image brightness (before vs. after) indicates rapidly increasing calcium concentration in the cells.
