• Pancreatic stellate cells (PSCs) are a key cellular component of the pancreatic tumor microenvironment and are considered to contribute to tumor invasion and metastasis. Multiple cytokines and growth factors derived from PSCs are involved in malignant cancer progression, including hepatocyte growth factor (HGF). However, the molecular mechanisms by which HGF regulates cancer invasion and metastasis have not been completely elucidated. Here, we report that two pancreatic cancer (PC) cell lines, Panc-1 and SW1990, displayed different invasive and migratory abilities after treatment with HGF secreted by PSCs. We found that HGF enhanced the invasive and migratory capacity of Panc-1 cells because of P53 deficiency, leading to overexpression of c-Met, which was regulated through P21. Additionally, our data showed that HGF/c-Met-mediated invasion and migration required the upregulation of survivin expression. In conclusion, PSCs promote PC cells invasion and migration via the HGF/c-Met/survivin pathway, which is negatively regulated by P53/P21.
