(C) E5.75 embryo cut longitudinally through the L-R axis (red-dashed line in B) showing GFP expression in the AVE. (D) E5.75 embryo cut longitudinally through the L-R axis after 4 days culture stained for alkaline phosphatase-activity. Black arrow in D points to PGCs. Scale bar is 100 μm. (E) Quantification of the number or explant-pairs cut longitudinally through the L-R axis that exhibited PGCs after 4 days of culture in one explant-half (posterior), both explants-halves or in none of the explant-halves
