简要总结

Macrophages are derived from monocytes recruited to the tumor site and stimulated by specific chemokines secreted by tumor cells. These tumor associated macrophages (TAMs) have been postulated as being involved in the progression of cancer.

Based on our preliminary findings and on published data we hypothesized that macrophage-induced chemoresistance (MIC) can promote survival of pancreatic carcinoma cells during chemotherapy.

The overall goal of this study is to evaluate the mechanism of MIC in an in-vitro model of Pancreatic ductal adenocarcinoma (PDA).

methods:

  1. The human PDA cell line Panc1 will be grown in suitable conditions.
  2. Macrophages will be produced by incubating mononuclear cells from the blood of healthy donors in medium with M-CSF for 7 days.
  3. TAMs will be generated by culturing these macrophages with tumor-culture conditioning medium (TCCM) of PDA Cells for an additional 72 hours.
  4. Human pancreatic cells (PANC1) will be treated with gemcitabine following exposure to macrophages CM.
  5. Cell proliferation will be quantified by light microscopy and by an XTT Cell Proliferation Assay Kit.

结局指标

主要结局

proliferation and migration of PANC1 cell line in the tested groups.

时间窗: one day to get the blood samples, and a year after that to complete the basic research

the macrophages will be isolated from the blood we'll get from the healthy volunteers. the outcome measure is related to the basic research and not clinical so there's no symptom/outcome related to the participants.

次要结局

  • To determine whether direct cell-to-cell interaction or soluble factors participate in MIC.(a year from obtaining the blood samples)
