Quality assessment results per article.
Quality assessment results per article, grouped by protocol and neuron type, and listed chronologically. The earliest article per protocol is printed in bold. Reference numbers are indicated following the article authors and year. The quality criteria in Figure 2 have been indicated diagonally above each column. Topic categories have been indicated below the table. Please see Supplementary file 2 for detailed criteria. * Methodological articles were assessed using the same criteria as other articles. iPSCs, induced pluripotent stem cells; n/a, not applicable; PSCs, pluripotent stem cells.

Neural crest cell induction.
Timings and signaling cues used during the first phase of differentiation until neural crest induction per unique protocol. Duration of this phase per protocol is indicated by the horizontal black bars. Categories of similar approaches are indicated to the right of the figure. Molecules targeting similar pathways have been grouped by color. Colors also match the signaling cues in Figures 4—6. * Selection step yields optimal cell purity, but this is not required. † Gomez et al., 2019 identified two optimal CHIR concentrations for neural crest induction, 3 µM and 10 µM. 10 µM was used for sympathetic neuron differentiation.

In vivo neural crest induction signaling requirements.
(A) General signaling requirements for distinct populations at the neural plate border. Left, a dorsal schematic view of the embryo and signaling cues (indicated in colored text) present near the neural plate border during early gastrulation are shown. Right, the temporal sequence of signaling cues required for distinct populations near the neural plate border in amniotes between gastrulation and neurulation is shown (based on Thawani and Groves, 2020). (B) Neuromesodermal progenitors arise in the tailbud during axial elongation under conditions of high Wnt and FGF signaling activation. Wnt and FGF concentrations form a rostrocaudal gradient, with highest concentrations in the tailbud. Right, neuromesodermal progenitors possibly contribute to posterior neural crest cell populations.

Rostrocaudal boundaries of vagal and trunk neural crest.
Lateral view of an embryo around the time of neural crest delamination. The rostrocaudal boundaries of vagal neural crest, which gives rise to parasympathetic neurons (Figure 6), are indicated by the light purple line adjacent to the embryo. The darker purple line indicates the rostrocaudal boundaries of trunk neural crest, which gives rise to sympathetic neurons (Figure 5). In later developmental stages, as axial elongation progresses, (sacral) neural crest continues to be formed caudally from trunk neural crest.

Sympathetic neurogenesis.
(A) Timings and signaling cues used from neural crest induction until the end of sympathetic neuron differentiation. Duration of this phase per protocol is indicated by the horizontal black bars. Total durations of this phase exceeding the width of the graph are indicated to the right of the graph. Molecules targeting similar pathways have been grouped by color. (B) Transverse cross section of the trunk of an embryo during neural crest migration. Signaling requirements for ventral neural crest migration and sympathetic specification are indicated by bold text. Signaling cues targeted by the protocols in (A) are indicated with colored text matching those in the figure legend. (C) Schematic view of the signaling requirements for sympathetic precursor proliferation and target innervation. The discontinuous axon and blood vessel represent the large distance from the sympathetic ganglia to their peripheral targets. * Aphidicolin selection yields optimal cell purity.
