(A) Pancreatic tumorsphere formation assays were performed on freshly isolated mouse pancreatic tumor cells or circulating tumor cells from peripheral blood modified from Rovira, et al32 (link). Briefly, pancreatic tumors from 10-13 week old REM1-KPf/fC or REM2-KPf/fC mice were dissociated and FACS sorted for YFP+ and YFP- or EpCAM+/GFP+ and EpCAM+/GFP- cells, respectively. 100-500 cells were suspended in 100μl DMEM F-12 (Gibco, Life Technologies) containing 1x B-27 supplement (Gibco, Life Technologies), 3% FBS, 100mM-mercaptoethanol (Gibco, Life Technologies), 1x non-essential amino acids (Gibco, Life Technologies), 1x N2 supplement (Gibco, Life Technologies), 20ng/ml EGF (Gibco, Life Technologies), 20ng/ml FGF2 (Gibco, Life Technologies), and 10ng/ml ESGRO mLIF (Millipore). Culture media for circulating tumor cells also contained 20ng/ml mHGF (R&D Systems). Cells in media were plated in 96-well ultra-low adhesion culture plates (Costar) and incubated at 37°C for 7 days. Sphere images were obtained with a Nikon80i. Sphere size was measured using ImageJ 1.47v software.

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.
