Behavioral Assessments in Chronic PD Rats.

<p>(<b>A</b>) Apomorphine-induced rotations analysis revealed a significant improvement in chronic PD rats that received tNSCs cell therapy (Group II, n = 6, black round line) compared to the control group (Group I, n = 6, blank round line). (<b>B</b>) Bar tests (sec) improved at 3-week post-cell therapy. (<b>C</b>) Shortened step length and (<b>D</b>) stride length were significantly improved after 3-week post-cell therapy in PD rats. (<b>E</b>) Significant improvement in walking speed (cm/sec) in PD rats at 3-week post-cell therapy. (<b>F</b>) Significant shortening in base of support (mm) was seen at 3-week post-cell therapy. (<b>G</b>) A well-designed cage with a video camera for footprint analyses. (a): in normal rats, (b): in PD rats pre-cell therapy, and (c): post-cell therapy. Asterisk: compared to the control. Student’s t test: *:p<0.05; **: p<0.01; and ***: p<0.001.
