Table 3 Frequency of positivity of carcinoma cells for connexin43, MAD, Twist, vimentin, PCLγ, Tks5, and CXCR4 in paired primary tumors and metastasis of predominantly AC and SCC

From: Bulk tumour cell migration in lung carcinomas might be more common than epithelial-mesenchymal transition and be differently regulated
