From: Ependymal cilia decline and AQP4 upregulation in young adult rats with syringomyelia
Schematic diagram of secondary SCI induced by syringomyelia in our study. Cilia in ependymal cells played key roles during the process (upper). Cilia decline led to deconstruction of ependymal barrier and increased pressure in central canal. AQP4 upregulation may be a compensatory effect of spinal cord on water transport disorders like syringomyelia (lower)
