The images above show neuromuscular junctions in a control group (left images), a group with a sciatic injury (middle images), and a group with a sciatic injury where NANOG was expressed. The green shows presynaptic axons and synaptic vesicles; the red shows postsynaptic acetylcholine receptors (AChRs); and the yellow shows regions of overlap between the two. The asterisks indicate multiple innervations, and the arrows…
