Effects of cell density on nuclear localization of TAZ in bovine GCs. Granulosa cells were seeded overnight on coverslips in 6-well dishes at increasing cell densities from 0.125–0.50 × 106 cells/well. (A) Representative micrograph of GC plated at 0.125 × 106 cells/well; WW domain-containing transcription regulator 1 (TAZ; WWTR1) (a), alpha-tubulin (b), colocalization of TAZ and alpha-tubulin (c), 20× magnification of colocalization of TAZ and alpha-tubulin (d), TAZ (e), DAPI (e), colocalization of TAZ and DAPI (g), 20× magnification of colocalization of TAZ and alpha-tubulin (h). (B) Representative micrograph of GC plated at 0.25 × 106 cells/well. (C) Representative micrograph of GC plated at 0.50 × 106 cells/well. (D) Quantitative analysis of colocalization of TAZ with alpha-tubulin and DAPI. Data are represented as means ± SEM, n = 3 experiments. **Significant difference as compared to 0.125 × 106 cells/well, P < 0.05. Micron bar represents 20 μm (63×) and 50 μm (20×).
