Figure Lengend Snippet: AMH from granulosa cell conditioned medium suppresses MOSE growth in culture. A , AMH was immunodepleted from granulosa cell conditioned medium (GCCM) using an excess concentration of anti-AMH rabbit polyclonal antibody (Abcam ab84952) (Anti-AMH). Controls included normal culture medium (control) and granulosa cell conditioned medium that had no treatment (none), treated only with the affinity matrix used for IP (+ protein A/G), or non-specific pre-immune rabbit serum and Protein A/G (Pre-Ab). MOSE cultures were treated with the respective medium for 6 days, and relative cell number was determined by WST-1 assay, shown as mean ± s.d., with ∗ p < 0.05, as determined by an unpaired two-tailed Student’s t test. The error bars indicate multiple and potentially overlapping measurements. There was no significant difference (N.S.) between cell proliferation in control medium and anti-AMH immunodepleted granulosa cell conditioned medium; however, a significant difference was determined between cells grown in untreated granulosa cell conditioned medium (none) and anti-AMH immunodepleted granulosa cell conditioned medium. B , granulosa cells were isolated from wild-type or AMH knockout mice and grown in culture for 6 days. The conditioned medium was collected and incubated with MOSE cells for an additional 6 days. The effect of granulosa cell conditioned medium from normal wild type or AMH knockout mouse ovaries was compared to normal culture medium. MOSE cell proliferation was significantly decreased by growth in WT GCCM, determined as ∗ p < 0.05 by an unpaired two-tailed Student’s t test. C , MOSE cells were treated with TGFβ, EGF, or granulosa cell conditioned medium for 6 days, then collected in sample buffer, and analyzed by Western blot for the proteins indicated. D , images of cells treated with TGFβ, EGF, and conditioned medium collected from wild type (WT) or AMH KO granulosa cells grown in culture for 6 days.
Article Snippet: The Student’s unpaired two-tailed t test calculator offered online from GraphPad was used to compare and test for significance between two groups, where p < 0.05 is considered statistically significant.
