One normal human breast epithelial cell line (MCF-10A) and four BC cell lines (MDA-MB-231, MDA-MB-468, MCF7 and MDA-MB-415) were obtained from the Shanghai Cell Bank, Chinese Academy of Sciences (Shanghai, China). These cells were cultured in Dulbecco's modified Eagle's medium (DMEM; Gibco-BRL, Grand Island, New York, NY, USA) supplemented with 10% fetal bovine serum (FBS, Sigma-Aldrich, St. Louis, MO, USA). All the cells were maintained at 37°C in a humidified incubator with 5% CO2.

Forty BALB/cnu-nu female nude mice aged 5-6 weeks and weighing 16-20 g (SLACK, Shanghai, China) were housed in the specific pathogen-free (SPF) environment. Human breast cancer cell line MDA-MB-231 (Shanghai Cell Bank, Chinese Academy of Sciences) was maintained at 37°C in L-15 medium containing 10% FBS. When the cell confluence reached 100%, cells in the logarithmic growth phase were harvested, digested, and centrifuged, and then cells were resuspended in normal saline at a density of 2 × 107/ml. Each mouse was subcutaneously inoculated with 0.1 ml of cell suspension at the right axillary.

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.
