obsolete planar cell polarity pathway involved in gastrula mediolateral intercalation (obsolete GO:0060775)
OBSOLETE. The series of molecular signals initiated by binding of a Wnt protein to a receptor on the surface of the target cell where activated receptors signal via downstream effectors including C-Jun N-terminal kinase (JNK) contributing to the interdigitation of cells along the mediolateral axis during gastrulation.
