Abstract

Cell transplantation offers a novel therapeutic strategy for stroke; however, how transplanted cells function in vivo is poorly understood. We show for the first time that after subacute transplantation into the ischemic brain of human central nervous system stem cells grown as neurospheres (hCNS-SCns), the stem cell-secreted factor, human vascular endothelial growth factor (hVEGF), is necessary for cell-induced functional recovery. We correlate this functional recovery to hVEGF-induced effects on the host brain including multiple facets of vascular repair and its unexpected suppression of the inflammatory response. We found that transplanted hCNS-SCns affected multiple parameters in the brain with different kinetics: early improvement in blood-brain barrier integrity and suppression of inflammation was followed by a delayed spatiotemporal regulated increase in neovascularization. These events coincided with a bimodal pattern of functional recovery, with, an early recovery independent of neovascularization, and a delayed hVEGF-dependent recovery coincident with neovascularization. Therefore, cell transplantation therapy offers an exciting multimodal strategy for brain repair in stroke and potentially other disorders with a vascular or inflammatory component.

  • Transplantation of allogeneic mesenchymal stem cells and neural stem cells can stabilize BBB and promote BBB integrity in stroke models, in addition to neuroprotection.

    “For example, transplantation of allogeneic mesenchymal stem cells and neural stem cells, in addition to offering neuroprotection, can stabilize BBB and promote BBB integrity as shown in stroke models (260, 463, 578).”

    From Blood-Brain Barrier: From Physiology to Disease and Back (2019) · cites this paper as [260]

    The Results report reduced BBB leakage after human neural stem-cell transplantation in stroke-model rats, and the Discussion reports prior findings that neural stem cells or mesenchymal stem cells improve BBB integrity. However, the Methods describe human cells transplanted into rats, not allogeneic transplantation, and these passages do not establish neuroprotection by both cell types. (LLM, conf=0.86)

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.
