Blue, trophectoderm (TE); yellow, epiblast (EPI—ICM exhibiting exclusive Nanog expression); green, primitive endoderm (PrE—ICM exhibiting exclusive Gata4/6 or Sox17 expression, as appropriate); orange, uncommitted ICM cells (exhibiting co-expression of both Nanog and Gata4/6 or Sox17, as appropriate); and grey, ICM cells negative for either assayed marker. (d) Bar charts show average number of cells allocated to each specified ICM lineage, as judged by the indicated IF staining regime employed. Error bars represent s.e.m. and asterisks denote statistical significant differences in cell number between the vehicle control (+DMSO, black bars) and p38-Mapk14/11 inhibited (+SB220025, grey bars) embryo groups, according to two-tailed Student's t-test, with *p < 0.05 and **p < 0.005 confidence intervals. Yellow asterisk denotes increase in cells positively immunofluorescently staining for both EPI and PrE ICM markers using anti-Nanog and anti-Gata6 (an early PrE marker) antibodies.

Detection of Mouse GATA-6 by Western Blot Reduced expression of the primitive endoderm markers Gata4 and Gata6 and increased expression of Nanog was observed in embryoid bodies following inhibitor of the Fgfr.Embryoid bodies were grown in different concentrations of AZD-4547 or 0.08% DMSO for 7 days.
