Co-injection of BMP4 MO with chordin MO reduced ICM expansion in chordin morphants. Upper panel: (A–B) ICM expansion in morphant embryos (A) and morphant embryos co-injected with BMP4 MO (B). A width of >3 or d3 somites was arbitrarily defined as the cutoff for ICM expansion. Lower panel: (C) Left: Frequency of ICM expansion in embryos injected with chordin MO (Chd, 0.75 ng), Chd MO (0.75 ng) + BMP4 (12 ng), ChdMO (0.75ng) + random sequence MO (12 ng). Right: Frequency of ICM expansion in embryos injected with ChdMO (0.15 ng) + TsgMO (6 ng), ChdMO (0.15 ng) + TsgMO (6 ng) + BMP4MO (12 ng), ChdMO (0.15 ng) + TsgMO (6 ng) + random sequence MO (12 ng). Each error bar represents 1 SEM. *P < 0.05. RS, random sequence MO (see Materials and methods). |
