Cancer cell lines were purchased from the American Tissue Culture Collection (ATCC) or Thermo Fisher Scientific. MDA-MB-231, BT-549, MCF7, DLD-1, and 4T1-luc cells were cultured in RPMI 1640 (Corning), HeLa, HEK293T, and HEK293FT cells in DMEM (Corning), MDA-MB-231-luc cells in MEM (Corning), and HCT116 cells in McCoy’s 5A (Corning). The above media were supplemented with 10% fetal bovine serum (FBS), 2 mM glutamine, and 100 U/ml penicillin and streptomycin. All in vitro experiments were performed using multiple-well plates or dishes pre-treated with Matrigel (BD no. 356234) except tumorsphere assays and ELDA that used ultra-low attachment plates and migration/invasion assays that used commercial 24-well plates with inserts. Glioblastoma stem cells (GSCs) were cultured in Neurobasal medium (Thermo Fisher Scientific no. 11360070) supplemented with B27 without vitamin A (Thermo Fisher Scientific no. A3353501), EGF, and bFGF (20 ng/ml each, R&D Systems), sodium pyruvate (Thermo Fisher Scientific no. 11360070), and GlutaMAX (Thermo Fisher Scientific no. 35050061).

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human MDA-MB-231, T47D, MCF7, SKBR3 and THP-1 cell lines were all obtained from Cell Bank of the Chinese Academy of Sciences (Shanghai, China) and passed the test of DNA profiling (short tandem repeat (STR) profiling method). All these breast cancer (BC) cells (MDA-MB-231, T47D, MCF7 and SKBR3) were cultured following the instructions of the American Type Culture Collection (ATCC, Manassas, VA, USA). For M2 tumor-associated macrophages (M2-TAMs) generation, as previously described, THP-1 cells were first treated with 200 nM Phorbol-12-myristate-13-acetate (PMA) (Sigma-Aldrich, USA) for 24 h, then PMA-THP-1 cells (polarized into macrophages) were cultured by the addition of conditioned media from BC cells (MDA-MB-231, T47D, MCF7 and SKBR3) for another 48 h. In a co-culture system, THP-1 cells were differentiated in upper chamber (0.4 μm pore) (Corning, USA), and BC cells (MDA-MB-231, T47D, MCF7 and SKBR3) were seeded in the lower chamber. After 48 h, TAMs or BC cells were harvested for further study.

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.
