Novel Metrics zur Charakterisierung von Embryonic Dehnung des Nematode Caenorhabditis elegans

Overview

This article details protocols for monitoring morphogenic defects during embryonic elongation in the nematode Caenorhabditis elegans. The aim is to identify genes that regulate these phases and characterize their roles along the antero-posterior axis of the embryo.
