ATCC 2a3 crl 3212 human derived cell lines

FaDu and <t>2A3</t> cells were suspended directly into a matrix metalloproteinase (MMP) labile bio-thiol activator which was then printed with its respective 4-arm maleimide PEG bioink to establish hydrogels upon component contact at room temperature. Both cell lines were printed into 8 different matrix conditions (PEG versus PEG fnc in stiffnesses of 0.7, 1.1, 3.0, and 4.8 kPa) for a total of 16 matrix conditions investigated in this study. High-throughput printing was achieved through the use of 96-well plates, with the printing process allowing for spatial control of different cell and gel types to create a customized system based on user-preference.

Viability stains demonstrate high viability of cell clusters over time. Hydrogel samples were collected at 1, 4, and 7 days of culture, stained to assess viability, and imaged via confocal microscopy as z-stacks. (a) Images of FaDu cells, in a PEG hydrogel of 1.1 kPa stiffness, at 1, 4, and 7 days of culture, show high cell viability (green) and few dead cells (red). The development of multicellular clusters over time tracks with observations from light microscopy in . (b) Final images of each cell type and gel condition, recorded at day 7 of culture, reinforce the varied cell response to each condition. Scale: x and y dimensions reflect 826 × 826 μm, and z dimension reflects 200 μm depth. Blue: DAPI (nuclei), Green: calcein-AM (live cells), Red: ethidium homodimer (dead cell nuclei); (c) Quantified viability from reconstructed z-stacks for FaDu (left) and 2A3 (right) cells, printed in each hydrogel stiffness, either in PEG or peptide-functionalized PEG hydrogels. Each bar reflects triplicate specimens, error bars reflect 95% CI. Comparisons were conducted for cell viability between PEG and PEG fnc matrices at each stiffness, * = p < 0.05. For Day 7 samples at the end of the experiment, letters identify statistically different results across four stiffnesses within the PEG (a, b) matrix or the PEG fnc (a’, b’) matrix, α=0.05.

Hydrogels enable cell survival and rapid proliferation to form multicellular clusters. Light microscopy images of each cell type in each hydrogel condition were captured over 7 days to assess cell proliferation and morphology changes. (a) Images of FaDu cells, encapsulated as single cells in a PEG hydrogel of 1.1 kPa stiffness, at 0, 2, 4, and 6 days of culture show progressive cell proliferation and formation of multicellular clusters. (b) Final images of each cell type and gel condition, recorded at day 7 of culture, demonstrate the varied cell response to each condition. All samples were seeded initially as single-cell suspensions under identical cell concentrations. Corresponding day 0 images for panel (b) are provided in Supporting Information Figure SI-1. Scale bar = 100 μm. (c) Mean cluster counts for FaDu and 2A3 cells in each matrix, normalized to the day 1 count. Each point represents triplicate repeats, and error bars reflect the 95% confidence interval. Despite some variation, cluster counts are statistically indistinguishable for all conditions.

Cluster morphology measures and modeling at day 7 timepoint identify impacts of cell type and matrix parameters. 3D reconstructions of calcein-AM green-stained cell clusters for each cell type, matrix stiffness, and composition permutation were analyzed in Imaris to obtain per-cluster measurements of (a) surface area and (b) volume, and generate (c) complexity as a measure of invasiveness. (a-c) Graphs show the median of each value, ± 95% CI, n= 2-3 replicate gels (red, blue, green, offset for visibility) per condition, and n∼50-200 clusters per gel replicate. (d) Population data were modeled using lmer to generate plots of predicted cluster area, volume, and complexity as a function of stiffness. Cluster area and volume measures at day 7 varied with both stiffness and cell type and were cross-correlated. Area and volume magnitudes were correlated with matrix composition at day 7, but their change with stiffness was independent of matrix. Predicted complexity values aligned for FaDu cells in both matrices and for 2A3 cells in PEG fnc , but with unique behavior for 2A3 cells in PEG.

Venn diagrams illustrate the number of significantly regulated genes under three conditions: hypoxia (green), irradiation (yellow), and the combination of hypoxia and irradiation (blue). Numbers in the overlapping areas indicate genes commonly regulated under the corresponding conditions. Genes were considered differentially expressed if they had an adjusted p-value (padj) <0.1. (E) Biological processes differentially regulated in FaDu and 2A3 HNSCC cell lines under hypoxia and combined hypoxia with gamma irradiation. The figure illustrates biological processes significantly upregulated (red) or downregulated (green) in FaDu and 2A3 cells in response to hypoxia alone or in combination with gamma radiation. The analysis was performed using the WebGestalt 2024 platform and included only genes that were consistently detected across all three independent biological replicates and met the inclusion criteria of adjusted p < 0.1 and |log 2 FC| ≥ 2.

The mice with 2A3 HNSCC tumours were treated IP with: 400 μ Ci 188 Re-C1P5 mAb on day 0; or 5 mg kg −1 per day cisplatin on days 0, 1, 2 followed by 400 μ Ci 188 Re-C1P5 mAb on day 3; or 5 mg kg −1 cisplatin alone on days 0, 1, 2; or left untreated. The mice with CasKi cervical tumours were treated IP with: 200 μ Ci 188 Re-C1P5 mAb on day 0; or 5 mg kg −1 per day cisplatin on days 0, 1, 2 followed by 200 μ Ci 188 Re-C1P5 mAb on day 3; or 5 mg kg −1 cisplatin alone on days 0. 1, 2; or left untreated.
