SCO-spondin is a protein that in humans is encoded by the SSPOgene.[5][6][7] SCO-spondin is secreted by the subcommissural organ, and contributes to commissuralaxon growth and the formation of Reissner's fiber, a fibrous aggregation of secreted molecules extending from the subcommissural organ to the end of the spinal cord.[8]
