|DVDY_23718_sm_SuppFigS3.tif||1784K||Supp. Fig. S3. Tg(isl1:gfp)rw0 reporter expression reveals that the facial motor neuron migration defect in olig2 MO-injected embryos is not affected by co-injection of p53 MO. Panels are images showing dorsal views of whole embryos with anterior to the left. A–C: Wild-type embryos. D–F: olig2 MO-injected embryos. G–I: olig2 MO-injected embryos co-injected with p53 MO. Arrows indicate posteriorly migrated facial motor neurons. Bar indicates facial motor neurons along their caudal migration. Cranial motor neurons are labeled “n.”|
|DVDY_23718_sm_SuppFigS4.tif||2480K||Supp. Fig. S4. olig2 is not expressed in r4 and olig2 loss of function has no effect on hoxb1a or prickle1b expression. A: Wild-type expression at 22 hpf of olig2 in r5 and r6 in blue and egr2b in r3 and r5 in red. B: qPCR of hoxb1a expression in wild-type, control MO-injected, and olig2 MO-injected embryos at 24 and 33 hpf. C: qPCR of prickel1b expression in wild type, control MO-injected, and olig2 MO-injected embryos at 24 hpf. Error bars represent standard deviation. P value calculated by Student's t-test is listed above each bar and compared to wild-type embryos.|
