Abstract
The pharyngeal arch arteries (PAAs) are transient embryonic blood vessels that make indispensable contributions to the carotid arteries and great vessels of the heart, including the aorta and pulmonary arteries1,2. During embryogenesis, the PAAs appear in a craniocaudal sequence to connect pre-existing segments of the primitive circulation after de novo vasculogenic assembly from angioblast precursors3,4. Despite the unique spatiotemporal characteristics of PAA development, the embryonic origins of PAA angioblasts and the genetic factors regulating their emergence remain unknown. Here, we identify the embryonic source of PAA endothelium as nkx2.5+ progenitors in lateral plate mesoderm long considered to adopt cell fates within the heart exclusively5,6. Further, we report that PAA endothelial differentiation relies on Nkx2.5, a canonical cardiac transcription factor not previously implicated in blood vessel formation. Together, these studies reveal the heart field origin of PAA endothelium and attribute a new vasculogenic function to the cardiac transcription factor Nkx2.5 during great vessel precursor development.

Supplementary Figure 1 Cartoons depicting nkx2.5+ heart field origin of PAA endothelium.
a, At 16 hpf (14ss), the bilateral nkx2.5+ ALPM (dark gray) contains progenitors for both cardiac and PAA endothelial lineages. b, As cardiac progenitors (red) migrate to the midline (18 hpf, 18ss) to form the primitive heart, nkx2.5+ PAA progenitors (light blue) remain lateral and begin to condense. c, As the heart tube elongates (30 hpf), nkx2.5+ PAA progenitors condense into 3 clusters with diffuse progenitors residing caudally. The anterior-most cluster (light gray) gives rise to non-PAA tissue within the face (data not shown). The 2nd cluster initiates expression of angioblast marker tie1 (green) and concomitantly downregulates nkx2.5 prior to forming PAA3. d, By 38 hpf, the 3rd cluster similarly adopts a tie1+ angioblast fate and subsequently forms PAA4. During similar stages, 2 undifferentiated caudal clusters emerge that are comprised of nkx2.5+ PAA progenitors specified in the heart field (light blue) and PAA progenitors initiating nkx2.5 expression de novo in the pharynx (dark blue). These caudal clusters form PAAs 5 and 6, respectively. e, By 60 hpf, PAAs 3-6 (green) are patent vessels expressing markers of terminal endothelial differentiation such as tie1, fli1a, and kdrl, but not the progenitor marker nkx2.5. f, Schematic diagram depicting the reciprocal relationship between nkx2.5 and tie1 expression during the PAA progenitor to angioblast transition. a-d, dorsal views, anterior up; e, lateral view, anterior left; angioblast cluster and corresponding PAA numbers indicated.
Supplementary Figure 2 ZsYellow is expressed in the anterior lateral plate and pharyngeal mesoderm of Tg(nkx2.5:ZsYellow) in patterns non-overlapping with hemangioblast or endodermal markers.
a, Gross evaluation of Tg(nkx2.5:ZsYellow) embryos at 4 dpf revealed robust ZsYellow fluorescence in the heart (H) and liver (L). b,c, ZsYellow transcripts (red) were detected in the anterior lateral plate mesoderm (ALPM), abutting hemangioblast markers etsrp71 (b) and scl (c). d,Tg(nkx2.5:ZsYellow); Tg(sox17:GFP) embryo immunostained with anti-ZsYellow and anti-GFP antibodies to highlight nkx2.5+ pharyngeal cells (red) and sox17+ pharyngeal endoderm (green), respectively. Red-only nkx2.5+ clusters (arrowheads) were detected in between green-only sox17+ endodermal pouches. e,f, ZsYellow+ populations were examined in endoderm-less bonnie and clyde (bon); Tg(nkx2.5:ZsYellow) embryos and their phenotypically wild-type (WT) siblings. A midline heart and bilateral pharyngeal clusters (arrowheads) were detected in WT siblings. bon mutants exhibited cardia bifida (asterisks) and significant populations of bilateral pharyngeal ZsYellow+ cells (brackets), demonstrating their non-endodermal nature. The un-clustered appearance of ZsYellow+ PAA progenitor cells in bon embryos likely reflects their lack of pharyngeal segmentation. WT, n = 78; bon, n = 25. g–p, Spatiotemporal comparison of endogenous nkx2. 5 and ZsYellow transcripts in wild-type and Tg(nkx2.5:ZsYellow) embryos. Transcripts for nkx2.5 andZsYellow were indistinguishable at 14ss (g,h), 18ss (i,j) and 28 hpf (k,l). While nkx2.5 transcripts disappeared specifically from pharyngeal mesoderm by 48 hpf (m,o), ZsYellow transcripts persisted in this region reflecting higher ZsYellow transcript stability (n,p). a,d,o,p lateral views, anterior left;b,c flat-mount dorsal views, anterior left; e-n dorsal views, anterior up; a-d, g-p n>20 embryos per group.

Embryos were imaged in the green and red channels immediately after photoconversion (merged image is shown in a) and again at 60 hpf [green (inset, b), red (b) and merged images (c) are shown; n = 2]. Cluster 3 gave rise predominately to endothelium in PAA4 with a minimal contribution to PAA5 (b,c). d-f, When the left ALPM was photoconverted as shown in Figure 2k, the right ALPM (d) was left unconverted (white box) as a contralateral control. Embryos were imaged in the green and red channels immediately after photoconversion (merged image is shown in d) and subsequently at 60 hpf [green (e) and red (f) images are shown; (n = 2)]. No red reporter fluorescence was detected in the right side PAAs (asterisks in f). g-i, Tg(nkx2.5:Kaede) embryos were pan-photoconverted at 14ss and immediately imaged in the green and red channels (merged image is shown in g) and subsequently at 30 hpf [green (h) and red (i) images are shown; n = 3].

a-f, Validation of the nkx2.5 antisense morpholino.a, Schematic diagram of the nkx2.5 pre-mRNA and mature mRNA transcripts. The morpholino target site (MO, red bar) and the primer pairs used for RT-PCR (green arrows) are shown. b, Agarose gel of RT-PCR amplification products from control and nkx2.5 morphant (MOnkx2.5) 28 hpf embryos. While both control and nkx2. 5 morphant embryos contained pre-mRNA transcripts (primer pair F1R1, 189 bp amplicon, lanes 2 and 5), nkx2. 5 morphant embryos lacked spliced mRNA transcripts (primer pair F1R2, 230 bp amplicon, lanes 3 and 6). Lane 1 contains a 100 bp molecular weight ladder, and lanes 4 and 7 contain 18S rRNA loading controls. c-e, in situ hybridization analysis of tie1 transcripts revealed fewer PAA angioblast clusters in morphant (d, n = 65) when compared to control embryos (CTRL c, n = 33). The asterisk in (d) labels a single PAA angioblast. This phenotype was rescued by co-injection of 50 pg full-length zebrafish nkx2.5 mRNA (e, mRNAnkx2.5 n = 57). f, Phenotypic quantification and rescue; two-tailed t test, **P = 0.001, no significant (ns, P = 0.0755) difference was observed between CTRL and nkx2.5 morphants rescued with nkx2.5 mRNA. g-i, Section immunofluorescence analysis of Nkx2-5+/+ (g) and Nkx2-5lacZ/lacZ (h,i) embryos at E9.5 highlighting PECAM+ endothelium (red), alpha-actinin+ outflow tract (OFT) myocardium (green), and DAPI+ nuclei (blue) (n = 5 per group). Nkx2-5lacZ/lacZ embryos contain PECAM1+ endothelial cells in rudimentary PAA lumens (arrowhead, h) or scattered in regions where the dorsal aorta (DA) and 3rd PAA would otherwise form (arrows, i). d–e, Confocal z-stack images of flat-mounted control (j) and nkx2.5 morphant (MOnkx2.5; k) Tg(nkx2.5:nZsYellow) embryos at 14ss immunostained for ZsYellow protein (red). l, Graph depicting quantification of nkx2.5+ nuclei in the ALPM of control (n = 5) and MOnkx2.5 (n = 6) embryos.

Supplementary Figure 5 Neither overexpression of nkx2.5 nor inhibition of FGF signaling suppresses PAA endothelial cell differentiation.
a-e, Embryos were injected with 100 pg full-length nkx2.5 mRNA (mRNAnkx2.5) and evaluated by in situ hybridization for scl expression in the ALPM at 7ss (a,b) or tie1 expression in pharyngeal clusters at 38 hpf (c,d). Expression of scl was severely reduced in the ALPM of nkx2.5 mRNA injected embryos (b) (n>20 per group). No significant (ns) difference (e) in the number of tie1-expressing PAA clusters was observed between control (c, n = 16) and nkx2.5 injected embryos (d, n = 26; two-tailed t test, P = 0.4481) across two experimental replicates. f,g Tg(cmlc2:EGFP) embryos were treated with DMSO or the FGF inhibitor SU5402 (10 μM) starting at 5ss and imaged at 48 hpf. Treated embryos exhibited a small ventricle, a phenotype known to arise from inhibition of FGF signaling. h-l, Tg(nkx2.5:ZsYellow) embryos were treated with DMSO and SU5402 (10 μM) beginning at the 5ss and imaged at 28 hpf (k,l) or fixed at 34 hpf for in situ hybridization (i,j). in situ hybridization for tie1 revealed equal numbers of PAA angioblast clusters (h) between control (i) and treated (j) embryos, (DMSO, n = 30; SU5402, n = 38; two-tailed ttest, P = 0.7254 across two experimental replicates). Interestingly, FGF-deficient embryos exhibited disrupted body vasculature as demonstrated by the absence of vessels in the eye and the LDA (bracket). ZsYellow+ clusters in the pharynx (arrowheads) were indistinguishable between control (k) and treated (l) animals, demonstrating effective segregation of the PAA and cardiac progenitors (n>20 per group). a,b,k,l dorsal views, anterior up; c,d,i,j lateral views, anterior left; f,g ventral views.
