Ectopic expression of N-cadherin perturbs histogenesis in Xenopus embryos.

Xenopus embryos express N-cadherin in a pattern similar to that observed in other species, and cells expressing Xenopus N-cadherin can bind to cells expressing chicken N-cadherin in vitro. To investigate the developmental role of this molecule, we injected mRNA encoding chicken N-cadherin into one blastomere of 2-cell-stage Xenopus embryos and examined the effect of its expression on their development. The ectopic expression of N-cadherin occurred in various regions of the injected embryos and induced abnormal histogenesis, such as thickening, clumping or fusion of cell layers. These results suggest that the precise quantitative and qualitative regulation of the expression of cadherins is essential to embryonic morphogenesis.
