Check if the same lab product or an alternative is used in the 5 most similar protocols
The human PDAC cell lines Panc02.03, Panc3.27, Miapaca-2, and the murine PDAC cell lines, Panc02, and KPCP1 were originally procured from ATCC (Manassas, VA). Miapaca-2 was cultured in DMEM medium, and the rest others were cultured in ATCC-recommended RPMI-1640 supplemented with 10% fetal bovine serum and maintained at 5% CO2 at 37 °C. For long-term storage, the cells were frozen in a 5% DMSO containing the respective tissue culture medium in liquid nitrogen. Cell viability assays were carried out using Trypan-blue exclusion method using Beckman Coulter Vi-CELL™ cell viability analyzer and Image analysis [25 ].

Cell lines were authenticated with GenePrint10 (Promega) through JHH Genetic Resource Core Facility and stored in −70deg C in aliquots when not in use. Cells were cultured with RPMI-1640 medium, with 10% FCS, 10% L-glutamine, 10% Na-pyruvate, 10% Penicillin/Streptomycin and 0.1% beta-ME. All reagents were from Gibco®. When co-cultured with sorted MDSC, the FCS concentration was 1–2%. CD14+ monocytes from healthy non-age matched volunteers were used for controls. Murine melanoma cell line B16, colon-cancer cell line CT26, and pancreatic cancer cell line Panc02 were obtained from ATCC. MOC1 murine head and neck cancer line was obtained from Ravi Uppaluri (Dana Farber).

The human pancreatic cancer cell lines PK8 and PANC-1 were obtained from the Japanese Collection of Research Bioresources Cell Bank (Osaka, Japan) and the RIKEN Bio-Resource Center Cell Bank (Ibaraki, Japan). The mouse pancreatic cancer cell line Panc02 is available from ATCC. The murine cancer cell line (Panc02) was provided by T. Moroishi (Department of Cell Signaling and Metabolic Medicine, Faculty of Life Sciences, Kumamoto University). Human CAFs were established from surgically excised pancreatic cancer samples (56 (link)). Mouse CAFs, as described in the literature (57 (link)), were obtained by isolation of fibroblasts from mouse skin and stimulation of the cells with 2 ng/mL recombinant murine TGF-β (R&D Systems) for 6 days. These cells were cultured in RPMI 1640 medium or DMEM containing 10% FBS (normal medium) and incubated at 37°C with 5% CO2.

Pancreatic Cancer Cell Line Maintenance

Check if the same lab product or an alternative is used in the 5 most similar protocols
Standard previously published cell culture methods were used to maintain pancreatic cancer cell lines, including murine Panc02 (NIH repository, DTP/DCTC/NCI[26 (link)]), PanIN 4313 [27 (link)], K8484 and DT8082[28 (link)] as well as human MiaPaca-2, Panc1, and BXPC-3 (ATCC; CRL-1420, CRL-1469, CRL-1687). Luciferase tagged cell lines were generated by infecting the cell lines with a commercial lentiviral titer for firefly-luciferase (Genecopoeia, LPP-FLUC-LV105-025 containing 1x108 TU/ml). Non-infected cells were eliminated after addition of puromycin (10ug/ml, Sigma). Luciferase expression was confirmed for each line through One-Glo analysis (Pierce).

B78-D14 [“B78”, obtained from Ralph Reisfeld (Scripps Research Institute) in 2002] melanoma is a poorly immunogenic cell line derived from B78-H1 cells, which were originally derived from B16 melanoma (Becker et al., 1996 (link); Haraguchi et al., 1994 (link); Silagi, 1969 (link)). B78-D14 cells lack melanin, but were transfected with functional GD2/GD3 synthase to express the disialoganglioside GD2 (Becker et al., 1996 (link); Haraguchi et al., 1994 (link)), which is overexpressed on the surface of many human tumors including melanoma (Nazha et al., 2020 (link)). B16-F10 melanoma was obtained from American Type Culture Collection (ATCC) in 2005. The murine pancreatic ductal adenocarcinoma cell line Panc02 was purchased from ATCC. Panc02, B78 and B16 cells were grown in vitro in RPMI-1640 (Mediatech) supplemented with 10% FBS, 2mMol L-glutamine, 100U/ml penicillin, and 100μg/ml streptomycin. Mycoplasma testing via PCR was routinely performed.

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.
