Fig 2. Immunofluorescence staining of OCT-4 in ‘8’-shaped hatching blastocysts.

Fig 2

Representative images showing the different shapes and distributions of ICMs in mouse ‘8’-shaped hatching blastocysts: compact ICMs were far away from zona opening (upper panel); scattered ICMs were around the small zona opening (middle panel); double ICMs with two obviously separated masses divided into each of the herniated blastocoels and were around the small zona opening (lower panel). ICMs were stained with anti-OCT-4 antibodies (red). All nuclei were labeled with Hoechst 33342 (blue). The scale bar is 50 μm.
