Alteration of mechanical stress and cell proliferation patterns of cell islands. (A-C) Mechanical stress patterns of the triangular cell island without stretching and with 2% or 8% stretching, respectively. (D-F) Cell proliferation patterns of the same cell island without stretching and with 2% or 8% stretching, respectively. Note that arrows indicate stretching directions. (Scale bars, 100 μm).
