Changes in Wnt ligand transcription levels in both term and preterm hAECs ( n=8).
Gene expressions levels of WNT2B, WNT5B, WNT7A and WNT10B were significantly higher in term hAECs compared with preterm hAECs. Statistical significance was determined with one-way ANOVA accompanied by the Bonferroni post-hoc test (*P<0.05; **P<0.01).
