We also detected the level of AT1 marker RAGE and AT2 marker SP-C, and found that anti-TN-C therapy partially recovered the expression of RAGE and SP-C in BPD-like mice (Fig. 7G), implying that TN-C may be involved with AT1/AT2 cell differentiation. The gene discussed is SFTPC; the disease is bronchopulmonary dysplasia.
