MRI of GBM-1-implanted rabbits.

<p>(A) T2-weighted scan showing hyperintense tumor unilaterally near the thalamus (red arrowhead). T1-weighted scan before (B) and after gadolinium injection (C) showing a lack of enhancement within the tumor.</p

Targeting of the intervertebral disc under C-arm fluoroscopy.

<p>An epidural anesthesia needle was advanced under fluoroscopic guidance until reaching the center of the nucleus pulposus. Injection of Omnipaque contrast confirmed its proper localization.</p

Regression lines show the presence of cells within particular sections in a function of distance between the magnet and the chamber.

<p>Statistically significant difference was observed between the cell presence in the upper and lower sections (marked by asterisk). Upper section = green line, middle section = red line, lower section = green line.</p

<i>Ex vivo</i> MR imaging of 1.0x10⁶ Molday ION-labeled MSCs injected in explanted spinal column.

<p>White arrow points to the hypointense region containing the cell deposit.</p

Prussian blue staining of disc tissue 2 weeks after injection of 3x10⁶ Molday ION-labeled MSCs.

<p>Iron positive blue precipitates are visible inside the transplanted MSCs.</p

Time course of sedimentation for SPIO-labeled (dashed line) and unlabeled (solid line) HUCB-NSC (n = 6) presented as means±SD (A) and regression lines (B).

<p>No statistically significant difference was observed between SPIO-labeled and unlabeled cells.</p
