| Sample type |
SRA |

|
| Source name |
tumor
|
| Organisms |
Homo sapiens; Mus musculus |
| Characteristics |
treatment: combo.72hr
tissue: COLO205 tumor
strain: CB.17/SCID (Taconic)
tissue: tumor
age: adult
genotype: WT
gender: male
|
| Treatment protocol |
When tumors reached 100-150 mm3, mice remained untreated or were treated by s.c. injection with hFc (control protein, 25 mg/kg), aflibercept (VEGF Trap, ziv-aflibercept, 25 mg/kg), a DLL4 blocker (REGN 1035, 10 mg/kg) or a combination (combo) of aflibercept plus anti-Dll4 antibody. 24hr and 72hr post treatment heart and tumor tissues were harvested.
|
| Growth protocol |
2x10^6 COLO205 human colon carcinoma cells were grown s.c. in male CB.17/SCID mice (Taconic).
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Tissues were minced, enzymatically digested for 10 minutes using 2.5 mg/ml collagenase Type II, 2.5 mg/ml collagenase Type IV (Gibco), and 0.5 mg/ml DNase (Sigma) in PBS / 1% BSA at 37°C, treated with DMEM containing 10% FBS and filtered (70-µm nylon filter; Falcon). Single cell suspensions were subjected to 1X PharMLyse for 4 (tumor) or 10 (heart) minutes, washed and subjected to dead cell removal kit (130-090-101, Miltenyi). The remaining cells were used for single cell sequencing.
Tumor single cell suspensions underwent a depletion step using the following FITC conjugated Abs: COLO205 cells were incubated with anti-CD24 (11-0247-42, eBioscience) and anti-E-Cadherin (324104, Biolegend) using 10 µl anti-FITC-beads for 1x10^6 total cells. The remaining cells were used for single cell sequencing.
Cellular suspensions (~6000 cells) were loaded on a Chromium Single Cell Instrument (10X Genomics) to generate single cell GEMs. Single-cell RNAseq libraries were prepared using version 1 Chromium Single cell 3’ Library, Gel beads & Mutiplex kit (10X Genomics).
