SCO-spondin

SCO-spondin is a protein that in humans is encoded by the SSPO gene.[4][5][6] SCO-spondin is secreted by the subcommissural organ, and contributes to commissural axon 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.[7]
