2014/12/19
The divergence of perturbative expansions which occurs for the vast majority of macroscopic systems and follows from Dyson’s collapse argument prevents the direct use of Feynman’s diagrammatic techniq...
Xenopus ADAM13 and ADAM19 are Important for Proper Convergence and Extension of the Notochord
ADAM Metalloprotease Convergence and Extension Embryo Gastrulation Mediolateral Cell Intercalation Xenopus laevis
font style='font-size:12px;'>
2014/12/10
Gastrulation is a fundamental process that reorganizes the primary germ layers to shape the internal and external features of an early embryo. Morphogenetic movements underlying this process can be cl...
