Figure Lengend Snippet: Expression of CAP markers and VEGF-A isoforms during human prenatal lung development. RT-qPCR analysis of the expression of universal capillary marker CA4 and CAP2 specific markers ( SOSTDC1 , HPGD, EDNRB, CA4, APLN, and TBX2 ) (A) and of total VEGF-A ( VEGF-Atot ) as well as each VEGF-A isoform ( VEGF-A121 , VEGF-A145 , VEGF-A165 , VEGF-A189 ) (B) in native human prenatal lungs aged from the late pseudoglandular to the early canalicular stages of development (week 10–20 of GA). Results are shown as a dot plot with mean ± SEM, n = 8–10, * p < 0.05, ** p < 0.01, *** p < 0.001. (C) Visual summary of the VEGF-A isoforms and CAP2 markers expression during human prenatal lung development. Image created by Biorender.com .

Figure Lengend Snippet: Effect of VEGF-A isoforms on human prenatal lung explant morphology. Representative pictures of the human prenatal lung explant cultures, either untreated or treated with the different VEGF-A isoforms alone or in combinations (VEGF-A121, VEGF-A145, VEGF-A165, VEGF-A189, VEGF-A121-145, and VEGF-A121-145–189) for 48 h. Photos were taken at time 0 (left, (A) and at 48 h (right, (B) . At 48 h, hematoxylin-eosin staining was performed to evaluate the histology of the explants (C) . Scale bar indicated by 50 µm.
