Figure 4From: Maintenance of human amnion epithelial cell phenotype in pulmonary surfactantSurfactant-treated hAECs retain the ability to differentiate into type II alveolar cells. (A) PBS-treated hAECs cultured in SAGM for 28 days. (B) Surfactant-treated hAECs cultured in SAGM for 28 days. (C) hAECs cultured in control media (DMEM/F12) for 28 days. Red stain denotes expression of surfactant protein-A, and Hoechst (blue) staining was used to label cell nucleus (n = 3, performed in duplicate for all conditions).Back to article page
