Substance P Administered after Myocardial Infarction Upregulates Microphthalmia-Associated Transcription Factor, GATA4, and the Expansion of c-Kit⁺ Cells

Figure 1

LV^7daysSP+I/R shows c-Kit⁺ GATA^high cell enrichment. Confocal images of GATA4 staining (red fluorescence) in conjunction with c-Kit (green fluorescence) and nuclear staining (blue fluorescence) in tissue sections of LV^7daysI/R and LV^7daysSP+I/R. Scale bars, 20 μm with a further magnified area indicated by the dotted white circle.
