mRNA expression levels of surfactant proteins in AECs. Expression of a SP-A (Sftpa), b SP-B (Sftpb), c SP-C (Sftpc), d SP-D (Sftpd), and e RAGE (Ager) in cultured primary AECs with or without co-culture of BMSC on day 21. <<AEC>>: AECs without co-culture with BMSC; <<AEC + BMSC>>: AECs co-cultured with BMSCs. Levels of each transcript were determined by real-time PCR and normalized to those of beta-actin (Actb). *P < 0.05 vs. AEC; ns not significant
