## Problem 127 — rank:6

**Title:** Transferable models of epithelial organogenesis

**Added binding assumptions (LaTeX):**

```latex
A coupled organ model must close the cell-density, proliferation, material-deformation and morphogen equations, including moving-boundary conditions and initial geometry. Distinguish shared parameters from the finite set of organ-specific inputs before validation. Declare separate shape and physiological-function observables; agreement with a selected geometry cannot establish functional organogenesis or unrestricted transfer to other organs.
