Semaphorin signaling in the SNS development. A Neural crest cells, differentiated from the ectoderm, migrate and aggregate around the developing aorta. B The SEMA3A–NRP1 signaling axis regulates the migration of sympathetic neuron precursors to the appropriate position. C SEMA3A and SEMA3F synergistically act in sympathetic nervous system patterning, such as sympathetic gangliogenesis and axon guidance. This image was created with BioRender (https://biorender.com/)
