Quantitative changes over time of the post-traumatic central canal lumen, ependymal and periependymal regions at 1 mm cranial to the lesion epicenter. (A) Quantitation of central canal perimeter 1 mm cranial to the lesion epicenter indicates a progressive increase from day 1 to day 450 following injury. (B) Quantitation of ependymal region thickness 1 mm cranial to the lesion epicenter indicates a progressive decrease from day 1 to day 450 following injury. (C) Quantitation of ependymal region nuclear density 1 mm cranial to the lesion epicenter indicates an increase from day 1 to day 28 following injury, then a progressive decrease from day 28 to day 450 following injury. (D) The relation of ependymal region thickness to perimeter of the central canal lumen at all time points. Error bars represent standard error.
