Figure 1: Expression of the SCMC in mouse eggs and early embryos.

(a) Mouse zygotes were fixed in the oviduct, embedded in paraffin and sectioned (4 μm). The sections were stained with rabbit anti-TLE6 and imaged with confocal microscopy. Scale bar, 20 μm. (b) Same as a, but with rabbit anti-FLOPED antibodies. (c) Same as a, but with rabbit anti-MATER antibodies. (d) The location and proximity of FLOPED and TLE6 in eggs and zygotes from normal females were determined with a proximity ligation assay (PLA) using rabbit anti-FLOPED and anti-TLE6 antibodies. After staining, the eggs/embryos were imaged by confocal and differential interference contrast (DIC) microscopy. Scale bar, 20 μm.
