Hart’s staining on PND7 and PND14 (n = 6). A Representative images for Hart’s staining on PND14. B Term hAEC injection improved secondary septal crest density to control levels. C Secondary septal crest density was decreased in the saline-treated injured group, hAEC and term EV injection normalized it to control levels. However, preterm EV treatment did not improve secondary septal crest density. (*p < 0.05, **p < 0.01, ***p < 0.001)
