Figure Legend Snippet: Spheroid formation, maturation, and functional CSC enrichment in HGSOC cell lines cultured under ultra‐low attachment (ULA) conditions. Representative brightfield microscopy images of OVCAR‐3 and OVSAHO cell lines cultured in ULA plates at relevant time points (4× objective). Yellow arrows indicate highly compartmentalized OVCAR‐3 spheroids, whereas red arrows denote overcrowded aggregates observed at extended culture durations (a). Schematic illustration summarizing spheroid morphologies observed under ULA conditions, including loose aggregates, compact spheroids, and compartmentalized spheroids (b). Quantitative analysis of spheroid diameter distribution and representative size comparison of highly compartmentalized OVCAR‐3 spheroids illustrating intra‐well heterogeneity within ULA cultures at Day 48 (10× objective) (c). Representative confocal microscopy images of an OVCAR‐3 spheroid at Day 48 including brightfield image, confocal z‐sections acquired at ∼2 µm intervals, and corresponding z‐stack projection (63× objective). Blue = DAPI (nuclei), green = α‐tubulin. Individual channels are shown separately to facilitate visualization of marker distribution. CD133‐PE monolayer negative controls and uncropped confocal images are provided in Figure S1 (d). Representative confocal microscopy images of additional aggregates and spheroids from the same culture (63X objective). Blue = DAPI, green = α‐tubulin, red = CD133‐PE. Individual channels are shown separately. CD133‐PE monolayer negative controls and uncropped images are provided in Figure (e). Growth inhibition curves and corresponding IC50 bar graphs for carboplatin, niraparib, paclitaxel, olaparib, cisplatin, and doxorubicin comparing OVCAR‐3 monolayer cultures (black bars) and ULA spheroids (gray bars). Viability was assessed using the NCI‐SRB assay (f). Data are presented as mean ± SD from three independent biological replicates. For SRB assays, each biological replicate contained technical triplicates. Statistical significance was determined using unpaired two‐tailed Student's t ‐tests or one‐way ANOVA where appropriate. * p < 0.05, ** p < 0.01, *** p < 0.001.

Figure Legend Snippet: Comparative benchmarking of CSC and EMT‐associated traits in HGSOC cells cultured using ULA and photopatterned GelMA platforms. Representative western blot images and corresponding quantitative bar graphs showing expression of CSC‐associated proteins SOX‐2, ALDH1A1, NANOG, and OCT‐4 in OVCAR‐3 and OVSAHO cultures. Protein levels were normalized to Vinculin and Calnexin, with representative loading control bands shown. Different loading controls were selected depending on target abundance, membrane compatibility, and subcellular localization. Quantification was performed using ImageJ (a). Representative flow cytometry pseudo‐dot plots with gates defined using unstained controls, and bar graphs summarizing the percentage of CD133‐PE, CD44‐FITC, CD117‐PE, and CXCR4‐FITC positive populations. Representative gating strategy is provided in Figure (b). Representative western blot images and quantitative bar graphs of EMT‐associated proteins Slug, Snail, TWIST1, vimentin, and fibronectin in OVCAR‐3 cultures (normalized to calnexin). E‐cadherin and N‐cadherin were additionally analyzed (normalized to α‐tubulin), with quantitative N‐cadherin/E‐cadherin ratios shown (c). Representative western blot analysis of stemness‐associated proteins in OVCAR‐3 cells cultured as 2D monolayer, 2D monolayer in spheroid enrichment medium, UV‐treated monolayer, ULA spheroids, and photopatterned GelMA (GelMA‐Pm) spheroids. Due to limited cell yield obtained from GelMA‐Pm cultures, only SOX‐2 and ALDH1A1 expression could be evaluated in these samples. Protein expression was normalized to GAPDH. Corresponding densitometric quantification is shown on the right. Full‐length uncropped blots are provided in Figure . (d). RT‐qPCR analysis of the stemness‐associated genes SOX‐2, NANOG, ALDH1A1, and c‐MYC in OVCAR‐3 cells cultured under 2D monolayer, 2D + sphere medium, 2D + UV, photopatterned GelMA (GelMA‐Pm), and ULA spheroid conditions. Gene expression levels were normalized to β‐actin and are presented relative to 2D monolayer controls (set to 1). Values above 1 indicate increased expression relative to monolayer cultures. Data represent mean ± SD from three independent biological replicates ( n = 3). Statistical significance was determined using multiple t ‐tests; significance symbols are defined as follows: p < 0.05 (*), p < 0.01 (**), p < 0.001 (***) (e). Data are presented as mean ± SD from three independent biological replicates. Statistical significance was determined using unpaired two‐tailed Student's t ‐tests or one‐way ANOVA where appropriate. * p < 0.05, ** p < 0.01, *** p < 0.001. Western blot images were cropped for clarity; non‐adjacent lanes from the same membrane are indicated by spaces. Full‐length blots are provided in Figure .

Schematic overview of the GelMA‐Pm fabrication workflow and representative image of square photomask‐generated polymerized GelMA structures visible to the naked eye (b). Quantitative comparison of spheroid number and spheroid diameter per mm 2 between ULA and GelMA‐Pm cultures (c). Representative brightfield microscopy images illustrating approximate spheroid diameter distributions within photopatterned GelMA cultures at Day 14, including representative OVCAR‐3 spheroids (∼100 µm) and smaller OVSAHO spheroids (∼50 µm) (d). Representative confocal microscopy images of GelMA hydrogels containing spheroids from OVCAR‐3 and OVSAHO cultures, demonstrating cell viability and spatial distribution (10× objective, with selected regions magnified to 20X as indicated by yellow boxes). Blue = DAPI (nuclei), green = α‐tubulin, red = CD133‐PE. Corresponding brightfield and fluorescence images of identical fields are shown (e). Data are presented as mean ± SD from three independent biological replicates. Statistical significance was determined using unpaired two‐tailed Student's t‐tests or one‐way ANOVA where appropriate. * p < 0.05, ** p < 0.01, *** p < 0.001.
