Figure 1From: The Sphingosine-1-phospate receptor 1 mediates S1P action during cardiac developmentS1P 1 R is the highest expressed S1P receptor in the developing heart. Real-time PCR analysis was performed on RNA samples isolated from either hearts only or embryos with hearts removed at (A) E9.5 and (B) E12.5. S1P receptor gene expression was compared to β-actin expression to determine the mean normalized expression. Each analysis was performed in triplicate.Back to article page
