Figure 1. DLL4 is expressed from the canalicular through alveolar stage of mouse and human lung development.

Figure 1

(A) DLL4 (red), PECAM (green), and nucleus (DAPI, blue) staining on mouse lung samples at E17.5, P2, P7, P14, and P28. E17.5 represents canalicular stage; P2 represents saccular stage; and P7, P14, and P28 represent early, middle, and completed alveolar stage. (B) DLL4 (red) and PECAM (green) staining on human lung slides at 22, 27, 36, and 39 gestational age weeks (22, 27, and 36/39 week represent human canalicular, saccular, and early alveolar stages). Scale bars: 10 μm. n = 4 per group.
