Hart’s staining on PND14 (n = 6–8). a Representative images for Hart’s staining. Scale bar = 100 μm. b, c Secondary septal crest density was decreased in the saline-treated injured group. Early intravenous (b) and intratracheal (c) injection of hAECs restored the tissue-to-air space ratio. d Both early and late treatment restored septal crest density. Data expressed as mean ± standard error of mean (SEM). Statistical significance determined with one-way ANOVA accompanied by the Bonferroni post-hoc test. *p < 0.05, **p < 0.01, ****p < 0.0001. hAEC human amnion epithelial cell, IT intratracheal, IV intravenous
