Cell Line Characterization and Authentication

Check if the same lab product or an alternative is used in the 5 most similar protocols
Bladder cancer cell lines UMUC3, TCCSUP, RT4, CRL2742, SW780, MGHU4, and UMUC9 were previously described (4 (link)). Lung and prostate cancer cell lines, A549 (16 (link)) and 22Rv1 (17 (link)) were obtained from the cell line repository at University of Colorado Cancer Center PPSR. Breast cancer cell lines HCC1806 and BT549 (18 (link)) were a gift from Dr. Richer at the University of Colorado. HEK293T cells were purchased from ATCC. All reagents and media were purchased from Invitrogen. All lines were authenticated by the University of Colorado Cancer Center PPSR core using an Applied Biosystems Profiler Plus Kit that analyzed 9 loci (Life Technologies 4303326). Cells were used in experiments within 6 weeks of thawing and were tested to be free of mycoplasma.

Authenticating Bladder Cancer Cell Lines

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human bladder cancer cell lines T24, 253J, UMUC3, J82, MGHU3 and HT1197 were authenticated by the University of Colorado PPSR core using an Applied Biosystems Profiler Plus Kit which analyzed 9 loci (Life Technologies 4303326). Cell ampules were resuscitated less than 2 months prior to being used in experiments in this study. Cells were cultured at 37 degrees Celsius, 5% CO2 in the following media. T24: Dulbecco’s Modified Eagle’s Medium/F12 (DMEM/F12) + 5% Fetal Bovine Serum (FBS), 253J and HT1197: Modified Eagle’s Medium (MEM) + 10% FBS + 0.1mM Nonessential Amino Acids (NEAA) + 1 mM Sodium Pyruvate, UMUC3 and MGHU3: MEM + 10% FBS + 1 mM Sodium Pyruvate, J82: MEM + 10% FBS + 0.1 mM NEAA. All reagents for media components were obtained from Invitrogen.

Cell Line Authentication and Culturing

Check if the same lab product or an alternative is used in the 5 most similar protocols
HCC lines and UMUC3 and T24 were obtained from American Type Culture Collection. UMUC3 and T24 were grown as described (Guin et al. 2014 (link)) except as noted below and were authenticated by the University of Colorado Cancer Center Protein Production Shared Resource using an Applied Biosystems Profiler Plus kit, which analyzed nine STR loci (Life Technologies, 4303326). After authentication, cells were frozen within 1–2 wk. Vials of cells were resuscitated <2 mo prior to being used in experiments in this study. All cells were cultured in DMEM (VWR Scientific) with GlutaminePlus (Atlanta Biologicals), 10% FBS (Seradigm), penicillin/streptomycin (GIBCO), glutamax (GIBCO), and sodium pyruvate (GIBCO), except HepG2 cells were cultured in EMEM (American Type Culture Collection) without sodium pyruvate.

Protocol for Cutaneous Melanoma Cell Line Cultivation

TAK-733 (Suppl Figure 1) was provided by Takeda Cambridge US, Inc. (Cambridge, MA) under a materials transfer agreement (MTA) and prepared as a 10mM stock solution in dimethyl sulfoxide (DMSO). For in vivo studies, this compound was prepared as a suspension in 0.5% methylcellulose in sterile water by brief vortexing followed by sonication for 10 minutes. The cutaneous melanoma cell lines were obtained from the American Type Culture Collection (ATCC; Rockville, MD) and were cultured according to their recommendations. All cell lines except SK-MEL24 and Hs852t were maintained in DMEM supplemented with 10% fetal bovine serum, 1% nonessential amino acids, 1% penicillin/streptomycin (Invitrogen; Carlsbad, CA) and were maintained at 37°C under an atmosphere of 95% O2, 5% CO2. SK-MEL 24 required 15% fetal bovine serum and Hs852t required a 10% CO2 atmosphere. Authenticity of all cell lines was verified by the University of Colorado Cancer Center DNA Sequencing and Analysis Core using the Profiler Plus Kit (Applied Biosystems; Foster City, CA). The data obtained was compared with ATCC data to ensure the cell line profiles had not changed with the latest profiling performed in January and February 2013.

Chimerism Determination Post-Transplantation

Post-transplantation D30 (range, 20-50) and 100 (range, 80-120) chimerism was determined using recipient PB or BM samples collected in EDTA. “Total donor cell” chimerism was performed on buffy coat leukocytes. “T-cell” chimerism was on Ficoll Hypaque separated lymphocytes from which purified CD3+ T-cells were isolated using immunomagnetic beads (Stem Cell Technologies Inc.). Pretransplantation PB samples were used to determine the donor and recipient genotypes based on 9 CODIS Short Tandem Repeat loci using the Applied Biosystems Profiler Plus® kit with the ABI 3130 capillary genetic analyzer to determine the alleles at each locus. Informative alleles unique to either donor or recipient were used to calculate % donor chimerism at each locus using the median peak intensity of amplicons attributable to donor divided by the sum of all amplicons at that locus. In cases where there were only unique recipient amplicons, % donor chimerism was calculated as (100 – % recipient chimerism). 95% confidence interval for chimerism was ±5%.

The CRC cell lines examined in this study were purchased from the American Type Culture Collection (ATCC), European Collection of Cell Cultures (ECACC) and Korean Cell Line Bank (KCLB)—Seoul National University. Cells were maintained and treated in RPMI media that contained 10% fetal bovine serum, 1% nonessential amino acids, and 1% penicillin/streptomycin. The cells were placed in an incubator at 37°C containing 5% CO2. The cells were routinely screened for the presence of Mycoplasma (MycoAlert; Cambrex BioScience). The CRC cell lines were treated with dasatinib when they reached ∼70% confluence. All cell lines were tested and authenticated in the University of Colorado Cancer Center DNA Sequencing and Analysis Core. CRC cell line DNA was tested using the Profiler Plus kit (Applied Biosystems). The data obtained were compared with cell line databases to ensure the cell lines have not changed.

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.
