Morphological alterations of human A549 pulmonary epithelial cells following HG exposure. Representative photomicrographs of cells cultured in (A) normal glucose conditions, (B) HG conditions, (C) hyperosmotic conditions, (D) HG conditions + tyrphostin AG490, (E) HG conditions + empty vector and (F) HG conditions + pcDNA3.1-SOCS3 expression vector. Photomicrographs were captured using an inverted microscope. Magnification, ×200. HG, high glucose; SOCS3, suppressor of cytokine signaling.
