CDH1 and erythema multiforme: Many studies have correlated EMT with the pathogenesis and development of EM (Matsuzaki and Darcha, 2012; Xiong et al., 2016; Lin et al., 2019; Zhang et al., 2019; Wang et al., 2020), inferring that the establishment of an endometriotic lesion would present the features of EMT, such as loss of cell polarity, disintegration of cell-cell junctions, increased in cell mobility, gain of N-cadherin expression and concomitant loss of E-cadherin expression (Bartley et al., 2014).
