Figure 3: Foot print analysis after intravenous cell transplantation after sciatic crush lesion. The animals with MSC transplanted nerve showed greater functional recovery as scored using the Sciatic Functional Index (SFI) than in sham control or control cell transplantation indicating that the cells have an enhancing effect for axonal regeneration and remyelination which results in improved functional outcome. Data are presented as means ± SE. Statistical evaluations were based on two-tailed t-test, χ 2 test (Origin; criterion, *significantly different, ).
