The signalling receptor MCAM coordinates apical-basal polarity and planar cell polarity during morphogenesis

It is unclear if there is an interaction between apical-basal (AB) polarity and planar cell polarity (PCP) pathways during morphogenesis. Here, the authors define a role for the melanoma cell adhesion molecule (MCAM), known to regulate PCP, in AB polarity via FGF signalling in vitro and in zebrafish.
