Here, we use a validated fetal–placental allometric scaling law and a first principles differential equations model of placental volume growth to generate biologically meaningful fetal–placental growth curves. The growth curves form the foundation for understanding healthy versus at-risk fetal growth and for identifying the timing of key events <i>in utero</i>. 2019-10-25 06:55:30 placenta placental volume differential equation logistic growth model fetal growth curves nonlinear regression
