Stepwise participation of HGF/MET signaling in the development of migratory muscle precursors during vertebrate evolution
... Here, we used comparative embryological analyses to show that the expression patterns of Hgf and Met in MMP development are highly diverse across vertebrate species. In HBM development, we found both Hgf and Met ...
