Soft tissue sarcoma (STS) cell lines (SK-LMS, SW982, RD, SW872) as well as primary sarcoma cell lines (ssRMS, BR-CS and WW-LMS) isolated from consented rhabdomyosarcoma patients` primary tumors, were a gift of Dr. med. C. Hinterleitner and Prof. G. Kopp (University of Tübingen).
Cell lines SK-LMS, SW982, RD, ssRMS, BR-CS, and WW-LMS were maintained in Dulbecco’s Minimum Essential Media (DMEM, Gibco) supplemented with 10% fetal bovine serum (FBS) (Sigma-Aldrich), 1% penicillin–streptomycin (Biochrom), 1% Sodium pyruvate and 1% MEM-Non-Essential Amino acids (100X) (Gibco), while the SW872 was maintained in RPMI supplemented with 10% fetal bovine serum (FBS) (Sigma-Aldrich), 1% penicillin–streptomycin (Biochrom), 1% Sodium pyruvate and 1% MEM-Non-Essential Amino acids (100X) (Gibco).
HEK239T cells used for lentiviral pseudo-virus production were obtained from ThermoFisher Scientific and maintained in Hyclone-DMEM medium supplemented with 10% FBS and 200 µM L-glutamine.
All cell lines were cultivated at 37 °C in 5% CO2 humidity.

The human U87 MG glioblastoma cancer (ATCC® HTB-14™) cell line was obtained from the American Type Culture Collection (ATCC, Virginia, United States). Dulbecco's Minimum Essential Media (DMEM), Eagle’s Minimum Essential Media (EMEM), Fetal bovine serum (FBS) and Phosphate Buffer Saline (PBS) were purchased from Life technologies (Pty) Ltd. (Fairlands, Johannesburg, RSA). The 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide (MTT), Dimethyl Sulfoxide (DMSO), Trypsin, and all other chemicals and reagents were of analytical grade and acquired from Merck (Pty) Ltd. (Modderfontein, Johannesburg, RSA). The U87 cell line was maintained in DMEM:EMEM (1:1), supplemented with 10% heat-inactivated FBS and grown at 37°C in a humidified incubator set at 5% CO2. Cells were sub-cultured with 0.25% (w/v) trypsin 0.53 mM ethylenediaminetetraacetic acid (EDTA) for a maximum of 15 min every 2 and 3 days after they had formed an 80% confluent monolayer.

Isolation and Culture of Murine Macrophages and Dendritic Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
RAW264.7 macrophages (ATCC) were cultured in Dulbecco’s Minimum Essential Media (DMEM, Life Technologies), supplemented with 10% (v/v) FBS, 1% (v/v) penicillin-streptomycin (PenStrep), and 1% (v/v) L-glutamine and cultured at 37°C and 5% CO2. Bone marrow derived dendritic cells (BMDC) were isolated from wild-type C57/BL6 mice (Taconic) as described previously.[32 (link)] Briefly, mice were euthanized by CO2 inhalation and femurs and tibiae were collected and sterilized in 70% (v/v) ethanol. Marrow cavity plugs were washed out using PBS. BMDC were resuspended in DMEM (Sigma Aldrich) and supplemented with 10% (w/v) bovine calf serum, 100 unit/mL penicillin, 100 µg/mL streptomycin, 2 mM L-glutamine, and 15 ng/mL granulocyte macrophage colony-stimulating factor (GM-CSF), plated onto 150-mm dishes and cultured at 37°C and 10% CO2. Three days post-isolation, 80% of the non-adherent cells were removed and centrifuged at 300 g for 5 minutes at room temperature and fresh medium was added. Five days post-isolation, loosely adherent BMDC were collected and resuspended at 1x106 cells/mL. Cells were used between 7 and 10 days post-isolation.

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.
