Un-normalized mRNA Ct values for TGFβ1 (A.), TGFβ2 (B.), MUC5AC (C.), activin A (D.), and FSTL3 (E.)by BECs at P1 (n = 6 asthma donors, n = 6 healthy donors), P2 (n = 6 asthma donors, n = 6 healthy donors), P3 (n = 4 asthma donors, n = 6 healthy donors), P4 (n = 6 asthma donors, n = 6 healthy donors), and P5 (n = 6 asthma donors, n = 6 healthy donors) are presented as individual data points for each donor cell line. Here, TGFB1 is linked to asthma.
