In Vivo Comparison of Developmental Potential
GFP+ ESCs were FACS sorted for PECAM and/or PDGFRα and injected into recipients blastocysts. Scale bar, 100 μm.
(A) E6.5 chimeric embryo generated from epiblast-primed cells showing the contribution to the embryo proper.
(B) E6.5 chimeric embryo generated from double-positive cells showing the contribution to the embryo proper.
(C) E6.5 chimeric embryo generated from double-positive cells showing the contribution to the VE (arrowhead).
(D) E6.5 chimeric embryo generated from double-positive cells showing the contribution to the PE (arrow).
(E) E6.5 chimeric embryo generated from PrE-primed cells showing the contribution to the VE (arrowhead).
(F) E6.5 chimeric embryo generated from PrE-primed cells showing the contribution to the PE (arrow).
