Figure 5: 90Sr exposure induces adipocytic differentiation.

(a) Representative image of Oil Red O staining of MS5 cells. Lipid droplets are stained in red, nuclei in blue. (b) Frequency of differentiated cells after one week of exposure to 90Sr (one-way ANOVA, F(3, 68) = 9.251, **p < 0.001). (c) Relative mRNA expression of the main adipocyte markers: Lpl, Adipoq and Fabp4 in MS5 after one week of contamination with 90Sr (one-way ANOVA, n.s.). Results are presented as mean ± standard deviation (SD) (arbitrary units, A.U.).
