EPCAM and neoplasm: A comparative analysis of the mHsp70 and EpCAM expression on non-adherent and adherent A549 (Figure 2B) cells revealed a higher expression of EpCAM on the adherent, epithelial-like cell population (A549, EpCAM: 64%) compared to the non-adherent, mesenchymal-like (A549, EpCAM: 46%) tumor subpopulation that dropped significantly upon treatment with TGFβ and L-lactic-acid (Figure 2B).
