Fig. 1. Pdgfr
is localised to the PrE layer of E4.0 blastocysts
and blastocyst outgrowths. (A) Pdgfr
is co-expressed with
Gata4 in the PrE of E4.0-4.5 blastocysts. (B-E) Co-expression of GFP in
E4.0 and E4.5 Pdgfr
H2B-GFP/+ embryos with Pdgfr
protein (B), and with the PrE markers Gata6 (C), Gata4 (D) and Dab2 (E).
(F) GFP is co-expressed with Gata4 in Pdgfr
H2B-GFP/+
blastocyst outgrowths after 72 hours of culture. Each row represents one
embryo. All panels show single optical sections. bf, bright field; green,
Pdgfr
(A) and GFP (B-F); red, Pdgfr
(B), Gata4 (A,D,F), Gata6
(C) and Dab2 (E); blue, Hoechst. Scale bar: 20 µm.
