Fig. 10From: Assessing the impact of gestational age of donors on the efficacy of amniotic epithelial cell-derived extracellular vesicles in experimental bronchopulmonary dysplasiavon Willebrand factor (vWF) immunohistochemistry in mouse lung tissue at PND 7 and 14 (n = 6). A Representative images for vWF staining on PND14. B, C The average number of vessels per field of view on PND7 (B) and PND14 (C). The average number of vessels with diameter ≤ 50 µm (black bars) was decreased in saline-treated injured mice, which was restored after hAEC and term EV treatment on both PND7 and PND14. There was no difference in the numbers of larger blood vessels (> 50 μm, grey bars) between groups. (*p < 0.05, ** p < 0.01)Back to article page
