Time course of <i>Jag1</i> gene expression in <i>Jag1</i> conditional/null mouse liver samples.

<p>Measurement of <i>Jag1</i> expression in whole mouse liver by real time PCR reveals that <i>Jag1</i> expression is significantly decreased in <i>Jag1</i> conditional/null mutant livers at newborn and 2 week time points. At 3 and 4 weeks of age, <i>Jag1</i> expression is not significantly decreased in whole liver, possibly corresponding to increased <i>Jag1</i> expression in other cell types within the liver.
