Photomicrographs of immunohistochemistry. E-cadherin (A-C); CD44 (D-F); SP-A (G-I); Phospho-c-Met (J-L). Compared with AMPC, increased E-cadherin and decreased CD44 membrane immunostaining were found in SMPC. Moreover, SP-A cytoplasm and Phospho-c-Met membrane immunostaining were decreased in SMPC (×400). SMPC, stromal micropapillary component, left panels; AMPC, aerogenous micropapillary component, middle panels; nMPC, non-micropapillary component, right panels.
