Abstract

A cell delivery strategy was investigated that was hypothesized to enable magnetic targeting of endothelial cells to the steel surfaces of intraarterial stents because of the following mechanisms: (i) preloading cells with biodegradable polymeric superparamagnetic nanoparticles (MNPs), thereby rendering the cells magnetically responsive; and (ii) the induction of both magnetic field gradients around the wires of a steel stent and magnetic moments within MNPs because of a uniform external magnetic field, thereby targeting MNP-laden cells to the stent wires. In vitro studies demonstrated that MNP-loaded bovine aortic endothelial cells (BAECs) could be magnetically targeted to steel stent wires. In vivo MNP-loaded BAECs transduced with adenoviruses expressing luciferase (Luc) were targeted to stents deployed in rat carotid arteries in the presence of a uniform magnetic field with significantly greater Luc expression, detected by in vivo optical imaging, than nonmagnetic controls.

  • Studies investigating the biological effects of typically sugar-coated SPION on dendritic cells, mesenchymal stem cells, endothelial cells and tumor cells have reported no impact on phenotype and cellular function.

    “Studies investigating the biological effects of (typically sugar-coated) SPION on dendritic cells [126], mesenchymal stem cells [127, 128], endothelial cells [129, 130] and tumor cells [131] have reported no impact on phenotype and cellular function.”
  • In rats with stainless steel stents in carotid arteries, intra-arterial injection of superparamagnetic nanoparticles preloaded into endothelial cells and exposure to a homogenous magnetic field showed high uptake of cells within the stent area, representing a novel strategy for site-specific delivery of cell-based therapy.

    “Polyak et al.102 used an alternative method to address delayed endothelial healing. Rats with stainless steel stents in their carotid arteries were intra-arterially injected with superparamagnetic nanoparticles that were preloaded into endothelial cells, making these cells magnetically responsive. The rats were subsequently exposed to a homogenous magnetic field that showed a high uptake of cells”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
