Neuregulin, or neu differentiation factor, induces cell
proliferation or differentiation through interaction with members of
the ErbB family of receptor tyrosine kinases. We report that neuregulin
can also induce profound morphogenic responses in cultured epithelial
cells of different origins. These effects include scattering of small
epithelial islands and rearrangement of larger cell islands into
ordered ring-shaped arrays with internal lumens. The ring-forming cells
are interconnected by cadherin- and

junctions. In confluent cultures, neuregulin treatment induces
formation of circular lumenlike gaps in the monolayer. Both cell
scattering and ring formation are accompanied by a marked increase in
cell motility that is independent of hepatocyte growth factor/scatter
factor and its receptor (c-Met). Affinity-labeling experiments
implied that a combination of ErbB-2 with ErbB-3 mediates the
morphogenic signal of neuregulin in gastric cells. Indeed, a similar
morphogenic effect could be reconstituted in nonresponsive cells by
coexpression of ErbB-2 and -3. We conclude that a heterodimer between
the kinase-defective neuregulin receptor, ErbB-3, and the coreceptor,
ErbB-2, mediates the morphogenetic action of neuregulin.
