(A) Schematic of experimental style demonstrates that embryos had been subjected to UV light at 48 hpf to photoconvert all neural crest cells from green to crimson. Cells that start Eos appearance after 48 hpf are tagged with unconverted Eos proteins (green). nc, neural crest cell; mg, electric motor glia. (B) In embryos subjected to UV light at 48 hpf, set at 80 hpf, and tagged with antibodies particular to acetylated HuC and tubulin, photoconverted cells (crimson, arrowhead) had been connected with sensory axons (blue), while unconverted cells (green, arrow) ensheathed electric motor axons (blue, arrow).

Confocal pictures of the embryo at 54 (A) and 72 (B) hpf display electric motor main glial cells (arrow) ensheathing electric motor axons (crimson) and sensory axons (arrowhead). (C) Confocal picture of a embryo at 54 hpf displaying cells along sensory axons (green, arrowhead) and engine axons (arrow). (D) Inside a larva at 8 dpf, two specific fascicles of sensory (arrowhead) and engine (arrow) axons had been seen.

Cot inhibitor-2 (A) Inside a mutant embryo subjected to UV light at 48 hpf and imaged at 72 hpf, MEP glia had been absent and OPCs (arrowhead) had been seen in the periphery. (B) Structures captured from a 15-h time-lapse film starting at 54 hpf inside a embryo. Amounts in lower remaining edges denote stage of embryo. Arrowheads denote OPCs which are ensheathing motor axons.

Excerpt from a 14-h time-lapse of a embryo from 58 to 72 hpf. cells (cell in the CNS labeled with black dot) extended dynamic processes into the periphery that contacted motor root glial cells (cell in periphery labeled with grey dot). After contact, OPCs remained in the CNS. At 90 min, the Supporting Video was frozen to display the OPC process in the periphery. Video on the left is annotated. Video on right is unannotated. Images were taken every 2.5 min, and the video runs at 10 fps.(MOV) pbio.1001961.s008.mov (2.8M) GUID:?73EC73BD-285C-41F0-B335-F9828DA073B7 Video S2: embryo that was imaged laterally (left) and turned digitally 90 degrees (right) to visualize an optical cross-section of the spinal cord. A cell migrated ventrally from the spinal cord, pinched at the MEP as it exited, and remained outside of the spinal cord. Video on the left is annotated with the dots marking the MEP glia cell. Video on the right is unannotated.
