Objective to introduce the research advances of chondroitin sulphate proteoglycans inhibitory role on injured spinal cord of rats.

Conclusion Finding a way to degrade chondroitin sulphate proteoglycans may promote regeneration of axons after spinal cord injury.

Their principle function is production of type III collagen, elastin, and proteoglycans of the extracellular matrix of the alveolar septa.
