Prof. Xijing He and his team from Xi’an Jiaotong University, China, injected chondroitinase ABC first into the edge of spinal cord damage zone at 1 week after spinal cord crush injury, thereby improving the microenvironment in the damage zone; and then, bone marrow mesenchymal stem cell suspension was injected on the next day.
