Nerves Are Closely Associated with LVs

(A) Lymphatic collectors of Prox1-GFP mice are closely associated with pan-neural marker TuJ1⁺ nerves (arrows).

(B) Tyrosine hydroxylase (TH)⁺ sympathetic nerves run along lymphatic collectors of Prox1-GFP mice and form synapses (synapsin I, zoom-in).

(C) Choline acetyltransferase (ChAT) GFP⁺ parasympathetic nerves, which form synapses (synapsin I), accompany mesenteric collectors (zoom-in).

(D) Collectors other than mesenteric collectors show no ChAT⁺ innervation. Synapsin I staining shows the presence of other types of nerves (zoom-in). Images were obtained using confocal microscopy.
