Rescue of BMP2-MO and GDNF-MO phenotypes by heat shock induced BMP2 using Tg(Hsp70:bmp2b-GFP) embryos, as well as by injecting BMP2b mRNA or GDNF mRNA. (a,b) Representative image of 66 hpf embryos obtained from control injection(78/84, 92.8%), (c,d) injection with BMP2b-MO alone(115/151, 76.2%) or (e,f) with BMP2b-MO plus heat-shocked at 10 hpf(120/146, 82.2%) or (g,h) with GDNF mRNA(110/153, 71.9%) or (i,j) with BMP2b mRNA (63/76, 82.9%), (k,l) injection with GDNF-MO alone(115/138) or (m,n) with GDNF-MO plus heat-shocked at 10 hpf(105/125, 84%). Arrowheads indicate phox2b expressing in the intestine. Bar, 100 μm.
