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 of morphogens controlling cell differentiation and tissue mechanics , to a two-phase poroelastic rheology , where one tissue phase consists of a poroelastic network made of cells and the other is the extracellular fluidpermeating between cells .
