Neural stem cell transplantation in central nervous system disorders: from cell replacement to neuroprotection

De Feo, Donatella, Merlini, Arianna, Laterza, Cecilia, Martino, Gianvito·2012·Current Opinion in Neurology

Abstract

PURPOSE OF REVIEW: Transplantation of neural stem/precursor cells (NPCs) has been proposed as a promising therapeutic strategy in almost all neurological disorders characterized by the failure of central nervous system (CNS) endogenous repair mechanisms in restoring the tissue damage and rescuing the lost function. Nevertheless, recent evidence consistently challenges the limited view that transplantation of these cells is solely aimed at protecting the CNS from inflammatory and neurodegenerative damage through cell replacement. RECENT FINDINGS: Recent preclinical data confirmed that transplanted NPCs may also exert a 'bystander' neuroprotective effect and identified a series of molecules - for example, immunomodulatory substances, neurotrophic growth factors, stem cell regulators as well as guidance molecules - whose in-situ secretion by NPCs is temporally and spatially orchestrated by environmental needs. A better understanding of the molecular and cellular mechanisms sustaining this 'therapeutic plasticity' is of pivotal importance for defining crucial aspects of the bench-to-beside translation of neural stem cell therapy, that is route and timing of administration as well as the best cellular source. Further insight into those latter issues is eagerly expected from the ongoing phase I/II clinical trials, while, on the other hand, new cellular sources are being developed, mainly by exploiting the new possibilities offered by cellular reprogramming. SUMMARY: Nowadays, the research on NPC transplantation in neurological disorders is advancing on two different fronts: on one hand, recent preclinical data are uncovering the molecular basis of NPC therapeutic plasticity, offering a more solid rational framework for the design of clinical studies. On the other hand, pilot trials are highlighting the safety and feasibility issues of neural stem cell transplantation that need to be addressed before efficacy could be properly evaluated.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Mertens et al. were able to precisely localize and sensitively image iron oxide nanoparticle-labeled collagen scaffolds by MRI in mice for up to 22 days.

    “They were able to precisely localize the implants and sensitively image them by MRI (Figure 9D).”
  • Scaffold labeling may allow for the visualization and quantification of scaffold degradation.

    “In addition, they provided initial experimental evidence showing that scaffold labeling may allow for the visualization and quantification of scaffold degradation [266].”

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.
