Early Embryo Granzyme G Expression (mouse)

Whole-mount embryo in situ hybridization (ISH) using a FITC-conjugated granzyme G oligonucleotide probe at different stages of normal mouse development.

• (A to C) One-cell stage mouse embryos.
• (D to F) Two-cell stage mouse embryos.
• (G to I) Four-cell stage mouse embryos.
• (J to K) Eight-cell stage mouse embryos.

• The left panels (A, D, G, and J) show embryos photographed under phase contrast imaging.
• The middle panels (B, E, H, and K) show embryos stained with Hoechst 33342 for DNA localization (blue) under fluorescence microscope observation.
• The right panels (C, F, I, and L) show embryos hybridized with a granzyme G oligonucleotide probe (green) under confocal microscopic observation.

Scale bar: 30 μm.

"The expression of members of the granzyme gene family of proteins (granzymes A-H, K, M), which encode serine proteases, has been documented in the secretory granules of cytolytic T lymphocyte lines [12]. Granzymes D, E, F, and G have also been shown to be expressed at gestation in the mouse uterus during the process of decidualization, in which rapid uterine cell growth and differentiation occurs [13]."
