doi: 10.34133/research.1105
Figure Lengend Snippet: (A) Calculated irreversible electroporation (IRE) lethal electric field thresholds for Pan02 mouse pancreatic cancer using a 3-dimensional (3D) collagen hydrogel; mean ± SD; n = 5. (B) COMSOL Multiphysics finite element model (FEM) representing subcutaneous mouse tumors with a 5-mm spacing shown. (C) Simulated percent tumor coverage by the lethal electric field using the subcutaneous FEM with randomized tissue conductivities and tumor sizes (4 to 8 mm); mean ± SD; n = 30. (D) In Vivo Imaging System (IVIS) imaging of FLuc-eGFP + Pan02 cells in immunodeficient NOD/SCID/IL2gc-KO (NSG) mice (m) follows complete ablation and subsequent microtumor recurrence after IRE treatment at 2,500 V/cm; n = 6. (E) Tumor scabbing and flattening at day 3 post-treatment. (F) Total photon flux within the tumor region of interest from the IVIS images; mean and range presented; multiple 2-tailed t tests between the data compared to the initial day 0 total photon flux; n = 6. (G) Measured tumor size over time from tumor inoculation; mean and range presented; multiple 2-tailed t tests between the data compared to pre-treatment tumor size on day 30; n = 6. ** P < 0.01; **** P < 0.0001. FLuc-eGFP, firefly-luciferase-enhanced green fluorescent protein. SAT, subcutaneous fat.
Article Snippet: Pan02 mouse pancreatic cancer cells (Cytion, 300501), AsPC-1 human pancreatic cancer cells (American Type Culture Collection [ATCC], CRL-1682), and Jurkat immortalized human T lymphocytes (ATCC, TIB-152) were cultured in RPMI 1640 medium (Thermo Fisher, 11875093) supplemented with 10% (v/v) fetal bovine serum (Fisher Scientific, FB12999102) and 1% (v/v) 10,000 U/ml penicillin–streptomycin (Gibco, 16140122).
