    "abstract": "Johnson-Kendall-Roberts (JKR) theory is an accurate model for strong adhesion\nenergies of soft slightly deformable material. Little is known about the\nvalidity of this theory on complex systems such as living cells. We have\naddressed this problem using a depletion controlled cell adhesion and measured\nthe force necessary to separate the cells with a micropipette technique. We\nshow that the cytoskeleton can provide the cells with a 3D structure that is\nsufficiently elastic and has a sufficiently low deformability for JKR theory to\nbe valid. When the cytoskeleton is disrupted, JKR theory is no longer\napplicable.",
