Spatiotemporal dynamic changes, proliferation, and differentiation characteristics of Sox9-positive cells after severe complete transection spinal cord injury

Studying the spatiotemporal dynamic changes of various cells following spinal cord injury (SCI) is of great significance for understanding the pathological processes of SCI. Changes in the characteristics of Sox9-positive cells, which are widely present in the spinal cord, have rarely been studied following SCI. We found that Sox9-positive cells were widely distributed in the central canal and parenchyma of the uninjured adult spinal cord, with...
