Fig. 6. Ectopic Notch2 signaling does not cause expansion of early chamber
marker expression into the developing AVC or IC. Neither Anf nor
Cx42 was induced following ectopic Notch pathway activation by
misexpression of Myc-tagged CSL-VP16 in stage 12 hearts or by Flag-tagged
mouse Hey1 and mouse Hey2. Analysis was as for preceding experiments.
