A novel, PCP‐dependent tissue organising principle coordinating morphogenesis between embryonic skin epidermal layers

Journal of Anatomy, EarlyView.
‘Outside‐in’ expression of Fz6 across multiple layers of mouse embryo epidermis is connected to Fz6 asymmetry in the basal layer plane. Fz6 loss‐of‐function correlated with failure to: coordinate axial bias of cell long axis orientation across epidermal layers, switch axial cell long axis orientation during suprabasal layer development and establish ...
