Figure 4. Stereological analyses of NeuN positive cells in Laminae I–IV, Laminae IV–V and Laminae VIII-IX after SCI and treatment.

Number of NeuN labeled neurons in all studied areas increased after pure and enriched alginate administration compared to saline. Among the experimental groups we observed statistical differences (***P < 0.001, **P < 0.01, *P < 0.05).
