Abstract

Platelet-derived growth factor (PDGF)–B–deficient mouse embryos were found to lack microvascular pericytes, which normally form part of the capillary wall, and they developed numerous capillary microaneurysms that ruptured at late gestation. Endothelial cells of the sprouting capillaries in the mutant mice appeared to be unable to attract PDGF-Rβ–positive pericyte progenitor cells. Pericytes may contribute to the mechanical stability of the capillary wall. Comparisons made between PDGF null mouse phenotypes suggest a general role for PDGFs in the development of myofibroblasts.

  • Pericyte-deficient mouse models caused by aberrant PDGF-BB/PDGFRβ signaling exhibit impaired BBB formation and maintenance.

    “Pericytedeficient mouse models caused by aberrant PDGF-BB/ PDGFR𝛃 signaling (365, 419, 436, 570, 575) exhibit impaired BBB formation (28, 59, 130) and maintenance (59, 436).”

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.
