Human PDAC cell lines PANC-1 and SW1990 were both purchased from American Type Culture Collection (Rockville, MD, USA). PANC-1 and SW1990 cells were cultured in Dulbecco’s Modified Eagle’s Medium (DMEM; Invitrogen, Carlsbad, CA, USA) supplemented with 8% fetal bovine serum (FBS; Sigma-Aldrich, St Louis, MO, USA) in a humidified chamber with 5% CO2 at 37 ℃. Mouse bone marrow was obtained and resuspended in DMEM to form a mononuclear white layer in 6-well plates (2×106 cells/mL, 3.5 mL/well; Falcon, Corning, NY, USA). After 2 hours, cells were washed 2 times and adherent cells (monocytes) were kept culturing in DMEM with 10% heat-inactivated FBS supplemented with 20 ng/mL macrophage colony-stimulating factor (M-CSF) for 7–9 days. Half of the medium was refreshed every 2–3 days. The purity of adherent cells after 3 days was analyzed using a multicolor panel of primary monoclonal antibodies against CD3, CD86, and CD11b. For macrophage differentiation, M1 was induced by 20 ng/mL M-CSF and 30 ng/mL lipopolysaccharides (LPS); M2a was induced by 20 ng/mL M-CSF and 20 ng/mL IL-4; M2b was induced by 20 ng/mL M-CSF, 20 ng/mL LPS, and 50 µg/mL immune complex; M2c was induced by 20 ng/mL M-CSF, 20 ng/mL IL-10, and 20 ng/mL TGFβ1; and M2d was induced by 20 ng/mL M-CSF, 20 ng/mL IL-6, and 20 ng/mL toll-like receptor (TLR) ligands.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
