Embryonic expression of mouse FGFRL1. (A) E7.5 embryo showing FGFRL1 expression in the most anterior and posterior embryonic territories. (B) Side view of an E8.5 embryo. (C, D) Posterior view of the embryo shown in (B) with focus on the brain and the trunk respectively. At this stage expression is clearly observed in the somites, the tailbud and the anterior and posterior brain. (E) Side view of an E9.5 stage embryo showing expression of FGFRL1 in the frontonasal region, the otic vesicle, the somites, the forelimb buds and the tailbud. (F, G) Side views of an E10.5 stage embryo showing expression similar to E9.5 embryos. At this stage the hindlimb buds are developing and also express FGFRL1. (H, I) Side views of E11.5 embryos. Expression is detected in the frontal region of the brain, in the branchial arches, the otic vesicle, the tailbud and in the chondrogenic regions of the trunk and limbs.
