Three-dimensional hydrogel culture systems support growth and determination of chemosensitivity of feline sarcoma and carcinoma cell lines
OBJECTIVE: To evaluate feline injection site-associated sarcoma (FISAS) and oral squamous cell carcinoma (FOSCC) cells in 3-D hydrogel-based cell cultures to determine chemosensitivity to carboplatin at concentrations comparable to those eluted from carboplatin-impregnated calcium sulfate hemihydrate (C-ICSH) beads.
SAMPLE: 2 immortalized cell lines, each from a histologically confirmed primary FISAS and FOSCC.
PROCEDURES: Hydrogels (10% wt/vol) were formed via UV exposure from methacrylamide-functionalized gelatin dissolved in PBSS. For each cell line, approximately 100,000 cells were encapsulated per hydrogel. Three cell-seeded 3-D hydrogels were evaluated for each carboplatin concentration (0, 150, 300, 450, and 600 µM) across 3 experiments. Drug efficacy was assessed by luminescence assay 72 hours after treatment. Growth of tumor cells treated with 300 µM or 600 µM carboplatin was evaluated using live-cell morphology imaging and confocal microscopy at 3, 7, and 14 days after treatment.
RESULTS: Mean half-maximal inhibitory concentration (IC50) values for FISAS and FOSCC cells ranged from 123 to 171 µM and 155 to 190 µM, respectively, based on luminescence assay. Viability at 3, 7, and 14 days for both cell lines at 300 µM carboplatin was 50%, 25%, and 5% and at 600 µM carboplatin was 25%, 10%, and < 5%.
CLINICAL RELEVANCE: 3-D hydrogel cell culture systems supported growth of feline tumor cells for determination of in vitro chemosensitivity. IC50s of each cell line were within the range of carboplatin concentrations eluted from C-ICSH beads. Cells from FISAS and FOSCC cell lines treated with carboplatin showed dose-dependent and time-dependent decreases in viability.
