Bone Marrow-Derived Cells that Populate the Adult Mouse Brain Preserve Their Hematopoietic Identity
Open accessAbstract
Cytogenesis in the adult brain can result from the recruitment of circulating precursors, but the proposal that some such cells transdifferentiate into neural elements is controversial. We have reinvestigated this issue by following the phenotypic fate of bone marrow cells expressing the green fluorescent protein transplanted into the systemic circulation of irradiated mice. Thousands of donor-derived cells were detected throughout brains of recipients killed 1-12 months after transplantation, but none displayed neuronal, macroglial, or endothelial characteristics, even after injury. Among those that crossed the endothelium of the cerebral cortex, >99.7% were identified as perivascular macrophages. Newly formed parenchymal microglia were found in significant numbers only in the cerebellum and at injury sites. Therefore, bone marrow does supply the mature brain with new specialized cells; however, mesenchymal precursors neither adopt neural phenotypes nor contribute to cerebral vascular remodeling. This continuous traffic of macrophages across the blood-brain barrier provides a vehicle to introduce therapeutic genes into the nervous system.

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.
