A total of 15 male SD rats aged 5–8 weeks and weighing 150–200 g were housed at 25 °C with 30% humidity and a 12 h light/dark cycle, with free access to water and food. At the beginning of the study, the animals were sacrificed by cervical dislocation. The ventricular tissues were cut into sections approximately 1 mm3 using ophthalmic scissors, then were washed twice in phosphate buffered saline without calcium or magnesium ions. The tissue pieces were moved into 10 mL centrifuge tubes for further digestion by trypsin and type II collagenase. The CMs were collected by centrifugation (TDZ4-WS, Xiangyi, Shanghai, China) at 500 × g for 5 min at room temperature. The isolated cells were cultured at 37 °C in a humidified atmosphere containing 5% CO2. The cell culture plates were precoated with 10 μg/mL of fibronectin and the cells were cultured in medium (CM media) containing Dulbecco’s-modified eagle medium (DMEM/F-12) with 2-hydroxyethyl (HEPES) (Invitrogen, Shanghai, China), 10% foetal bovine serum, 1% antibiotic-antimycotic solution (Invitrogen), 3 mM pyruvic acid, 2 mg/mL bovine serum albumin, 100 μg/mL ampicillin and insulin-transferrin-selenium solution (20 ng/mL, 11 ng/mL, and 13.4 pg/mL, respectively; Invitrogen), 5 μg/mL linoleic acid and 100 μM ascorbic acid (Nguyen et al. 2012 (link)). For all experiments, cells were cultured at 5 × 104 cells/mL unless otherwise stated.

Cell lines expressing pcDNA3, pcDNA3-HER2 were cultured and characterized using methods previously described [51 (link)]. Briefly, MCF7 cells engineered to express HER2 or contain the empty vector pcDNA were maintained in MEM supplemented with essential and non-essential amino acids (Invitrogen), Pyruvic acid, 10% glutamine and 10% FBS. Cells were harvested after they reached 80% confluence. Breast cancer cell lines BT474 and MDA453, which were originally derived from HER2-positive breast cancers that exhibited amplified HER2 [54 (link), 55 (link)] were purchased from ATCC and cultured using the recommended protocols.

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.
