Figure 1. Cripto-1 (CR-1) transgene activation in embryos upon Cre-mediated excision by EIIa-Cre mice.

Figure 1

(A) The strategy for the conditional expression of Cripto-1 and Luc transgenes. Please see the Materials and Methods for additional details on the strategy for the conditional expression of the transgenes. (B–E) Cre-mediated excision efficiency in embryonic hearts. (B,D) Whole-mount blue-stained embryonic hearts. (C,E) Histological sections of E11.5 (C) and E13.5 (E) embryonic hearts. The ventricular surface is indicated with a “*”, the atrial appendage is indicated with a “#”, and arteries are indicated with a “*”. (F) RT-PCR analysis using human-specific primer for human Cripto-1 transgene expression in RCLG/EIIa-Cre transgenic embryos and embryonic hearts. The cropped gels are used in Fig. 1F, and the full-length gel images are available in Supplementary Figure S28. The gels have been run under the same experimental conditions. (G) Western blot for the Cripto-1 protein in RCLG/EIIa-Cre transgenic embryos and their hearts. For (F,G), lane 1: E7.5+RCLG/Cre; lane 2: E7.5+Cre; lane 3: E8.5+RCLG/Cre; lane 4: E8.5+Cre; lane 5: E9.5+RCLG/Cre; lane 6: E9.5+Cre; lane 7: E10.5+RCLG/Cre; lane 8: E10.5+Cre; lane 9: E11.5+RCLG/Cre; lane 10: E11.5+Cre; lane 11: E12.5+RCLG/Cre; lane 12: E12.5+Cre; lane 13: E13.5+RCLG/Cre; lane 14: E13.5+Cre; lane 15: E14.5+RCLG/Cre; lane 16: E14.5+Cre; lane 17: E15.5+RCLG/Cre; lane 18: E15.5+Cre. The cropped blots are used in Fig. 1G, and the quantification of Cripto-1 expression and the full-length gel images are available in Supplementary Figures S6 and S28, respectively. The blots have been run under the same experimental conditions.
