Expression of SMILE in the mouse uterus during different phases of the oestrus cycle. (A) Immunolocalisation of SMILE protein in the luminal and glandular epithelial cells of the uterus during the mouse oestrous cycle. Bars =25 μm. (B) Expression of SMILE mRNA in cycle uteri as detected using real-time PCR. The values represent the mean ± S.E.M. from three duplicates, and the bar bearing different superscript indicates a significant difference between the mean values (P < 0.05).
