Abstract
Significance Spatiotemporal coordination of cell growth underlies tissue development and disease. Mechanical feedback between cells has been proposed as a regulatory mechanism for growth control both in vivo and in cultured cells undergoing contact inhibition of proliferation. Evidence beyond theoretical and correlative observations falls short. In this study, we probe the impact of mechanical tissue perturbations on cell cycle progression by monitoring cell cycle dynamics of cells in tissues subject to acute changes in boundary conditions, as well as tissue stretching and compression. Taken together, we conclude that the ability of tissues to support cell cycle progression adapts to the available space through a memory-free control mechanism, which may coordinate proliferation patterns to maintain tissue homeostasis.
