Before revision:  Our biphasic model of multicellular tissues incorporates turnover and transport of morphogens controlling cell differentiation and tissue mechanics in a single framework , where one tissue phase consists of a poroelastic network made of cells and the other is the extracellular fluidpermeating between cells .
After revision:  Our biphasic model of multicellular tissues incorporates turnover and transport in order to explore new routes to patterning. Our active description couples morphogen reaction-diffusion, which impact on cell differentiation and tissue mechanics in a single framework , where one tissue phase consists of a poroelastic network made of cells and the other is the extracellular fluidpermeating between cells .
