Nodal signaling inhibitor SB505124 blocks acvr1ba*-expressing cells from sorting. (A) Representative images of sox17:GFP expression under 0, 25 μM or 50 μM SB505124. Drug treatment began at 6 hpf, images were taken at 10 hpf. Animal pole view. (B) Quantification of sox17:GFP fluorescence intensity under 0, 25 μM or 50 μM SB505124. *** p<0.001. n=3. (C) sox17:GFP expression for embryos with or without injection of acvr1ba* and under no drug treatment or treated 50 μM drug SB505124 treatment. (D) Transplant of acvr1ba*-expressing cells into sox17:GFP background under DMSO control and 50 μM drug SB505124 treatment at 18hfp. |
