Human cell transplantation does not alter angiogenesis.

<p>A: Estimated length of blood vessels at the injury epicenter and at regions 1 mm rostral and 1 mm caudal to the lesion site were quantified using the Space Balls probe of StereoInvestigator. B: The injury epicenter was identified using DAPI immunofluorescent staining within the PE-CAM1-stained sections. C: While there was a trend toward an increase in blood vessel length at regions 1 mm rostral and caudal to the lesion, this difference was not statistically significant (<i>One-way ANOVA: F = 1.87, p = 0.17</i>). D: No significant differences in the blood vessel length were detected between the groups at the injury epicenter (<i>One-way ANOVA: F = 0.65, p = 0.53</i>). Scale Bar = 250 µm for A and B.
