ABSTRACT
A human neuronal cell line, hNT2.19, which secretes serotonin (5-HT) after differentiation, was used as a transplant source to improve motor dysfunction following severe contusive spinal cord injury (SCI). Also, environmental enrichment (EE) was added to the interspinal transplant treatment paradigm. Motor testing was performed weekly before and following SCI, with and without EE and/or cell transplant conditions. Motor recovery was maximal when both cell transplant and EE were used. Individual treatment paradigms also significantly improved foot rotation and reduced footfall errors but not stride length or base of support dysfunction. This recovery of motor function after SCI suggests that the combinatory use of serotonergic hNT2.19 cell grafts plus EE is a meaningful strategy to modestly improve motor dysfunction that accompanies contusive SCI.
