Sonic hedgehog (Shh) is one of key signaling molecules involved in the spatial patterning of teeth. By utilizing maternal transfer of 5E1 (an IgG1 monoclonal antibody against Shh protein) through the placenta to block Shh signaling, we investigated the changes in tooth patterning and in gene expression. We used microarrays to detect specific genes related with Shh signaling in tooth germs and identified some specific genes up- or down-regulated after blocking of Shh signaling activity. Gene-chip expression analysis was performed with RNA from mandibular tooth germs from embryos of pregnant mice at one\u00a0day after injection of 5E1 (an IgG1 monoclonal antibody against Shh protein; number of replicates =2), 40-1a (an IgG1 monoclonal antibody against \u03b2-galactosidase; number of replicates=2), cyclopamine (a specific Smo antagonist; number of replicates=2) or PBS (Phosphate buffered saline; number of replicates=2), using a Affymetrix mouse gene microarray.", "source": "http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-27429", "sample_source": "http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-27429/samples/"}
