In vitro evidences of epithelial to mesenchymal transition in low cell-density cultured human fetal hepatocytes

To conclude, the high cell-density culture system could be a useful model for in vitro studies requiring long-term cultures of hepatocytes, such as the development of pharmaceutical drugs and mechanisms of viral infections. The low cell-density culture system may provide additional insights into the origin of fibrogenic cells in the liver, thus contributing to the development of novel therapeutic approaches.
