Stem cells are identical in many scales, they share the same molecular composition, DNA, genes and genetic networks, yet they should acquire di?erent properties to form a functional tissue. Therefore, they must interact and get some external information from their environment, either spatial (dynamical fields) or temporal (lineage). In this work we test to what extent coupled chemical and physical fields can underlie the cell’s positional information during development. We choose the root apical meristem of Arabidopsis thaliana to model the emergence of cellular patterns. We built a model to study the dynamics and interactions between the cell divisions, the local auxin concentration and physical elastic fields.
