The 545-GFP cell line was derived from Brca1Co/Co MMTV-Cre (Brca1-MSK) mice, which develop only primary mammary tumors and have minimal metastatic ability, as determined by labeling with GFP. The 628-GFP cell line was also derived from Brca1-MSK mice, which not only develop primary mammary tumors but also develop multiple metastatic tumors in other organs, which were identified by the GFP label. B477 is a Brca1-WT mammary gland epithelial cell line, and G600 was derived from Brca1-MT mammary gland epithelial cells. T47D (catalog HTB-133), MDA-MB-231 (catalog CRM-HTB-26), MDA-MB-436 (catalog HTB-130), and HEK293T (catalog ACS-4500) cells were purchased from American Type Culture Collection (ATCC). All the cells above were cultured with high-glucose DMEM containing 10% FBS and antibiotics (100 μg/mL streptomycin and 100 U/mL penicillin; Gibco). All cell lines were cultured at 37°C in an atmosphere with 5% CO2. All other human breast cancer cell lines, including MDA-MB-436, MDA-MB-468, T47D, and HEK293T, were purchased from ATCC.

HCC1937 cells were maintained in RPMI 1640 medium (Life Technologies, Carlsbad, CA, USA). BT-549 cells were cultured in RPMI 1640 medium with 10% fetal bovine serum (FBS) and 10 μg/mL insulin. MDA-MB-231 and MDA-MB-468 cells were cultured in ATCC-formulated Leibovitz’s L-15 medium supplemented with 10% FBS, while MDA-MB-436 cells were grown in the same medium with 10 μg/mL insulin and 16 μg/mL glutathione. All the cells were maintained in a humidified incubator at 37°C with 5% CO2. Cells were passaged by trypsinization after reaching approximately 80%–90% confluence. The detached cells were seeded into a new flask at a density of 2.0 × 103 cells/cm2.

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.
