Figure Lengend Snippet: BPA, BPF, and BPS do not alter specific biomarker expression. Fluorescence microscopic images of immunocytochemistry analysis of BPA-, BPF-, and BPS-treated (0, 25, and 100 µM) spermatogonial stem cells (SSCs) (A), scale bar=50 µm, 40X magnification. Localization of specific proteins GFRα1 and PLZF (undifferentiated spermatogonia, red), VASA (germ cells, red), and c-Kit (differentiated spermatogonia, red), and DAPI (nuclei, blue), GFP (cultured germ cells enriched for SSCs, green). The ratio of marker-expressing cells per GFP + germ cells is presented by bar graph as mean±standard error of the mean (SEM) from three independent experiments. (B) Graphical representation of A is shown as the ratio of marker-expressing cells to GFP + germ cells presented as mean±SEM from three independent experiments. (C) Relative gene expression of undifferentiation biomarker genes ( Id4 , Bcl6b , Lhx1 , and Bmi1 ) are presented by bar graph as mean fold change±SEM from four independent experiments. Statistical analysis with one-way ANOVA and multiple comparisons by Dunnett’s test was conducted. There were no significant differences between treatments. BPA: bisphenol-A, BPF: bisphenol-F, BPS: bisphenol-S.
Article Snippet: SSCs were maintained in mouse serum-free medium (mSFM) supplemented with glial cell line-derived neurotrophic factor (GDNF) (10 ng/mL, 212-GD-50; R&D Systems), GDNF family receptorα1 (GFRα1) (75 ng/mL, 560-GR-100; R&D Systems), and basic fibroblast growth factor (1 ng/mL, 354060; BD Biosciences), as previously reported [ ].
