Tissue-specific Cre recombinase drivers and their relationship to cardiovascular lineages
| Cre driver | Time of deletion [E] | Tissue | Cardiac and vascular derivatives at E14.5 - E15.5 |
|---|---|---|---|
| Sox2Cre [19] | 6.5 | Epiblast | All embryonic tissues. |
| Wnt1Cre [15, 51] | 8.5 | Neural crest | Aorticopulmonary septum, conotruncal cushions, 3rd, 4th and 6th pharyngeal arch arteries. |
| Hoxa3Cre [22, 44, 52] | E8.0 - E9.0 | Pharyngeal arch lineages (endo, meso and ectoderm), caudal to the second arch (PA 3–6). | Pharyngeal arch arteries (smooth muscle cells), myocardium of a distal outflow tract and the base of the pulmonary trunk, outflow tract cushions. |
| Mesp1Cre [31–33] | 6.5–7.0 | Extraembryonic, lateral, cranio-cardiac, and pharyngeal mesoderm. | Myo-, endo- and epicardium, pharyngeal arch arteries. |
| Nkx2.5Cre [21, 36, 38] | 7.5–7.75 | Myocardial precursors of primary and secondary heart fields, pharyngeal endoderm and ectoderm of the first pharyngeal arch, proepicardium. | Myocardium; endothelium of coronary arteries, cardiac chambers, and valves; smooth muscle cells of the aorta and coronary arteries. |
