Figure 1. Identification of external genital progenitors in posterior lateral plate/anterior tail mesoderm of chick embryos.

Figure 1

(a) Schematic diagram showing a dorsal view of a stage 18 chick embryo. Colored dots show injection sites for embryos shown in panels b (DiI, red dot) and c (DiA, green dot). (b) Ventral view of a chick embryo 48 hours after injection of DiI into the somatic layer of the lateral plate mesoderm, lateral to the posterior region of the right hindlimb (depicted by the red dot in panel a). DiI labeled cells are seen on right side of genital tubercle (left in ventral view). (c) Ventral view of a chick embryo 48 hours after injection of DiA into the somatic layer of the lateral plate mesoderm, lateral to the posterior region of the left hindlimb bud (depicted by the green dot in panel a). DiA labeled cells are visible on left side of genital tubercle (right in ventral view). GT, Genital tubercle; HL, hindlimb. Red broken line marks the position of the urethral plate epithelium.
