We used low amounts of TGFβ1 (0.02 ng/mL) because they were comparable to those used by Yasutome et al. [49], they were previously demonstrated by us to induce the epithelial to mesenchymal transition in BxPC3 [28] and they were consistent with the amount released by pancreatic tumor cells [50]. The gene discussed is TGFB1; the disease is pancreatic neoplasm.
