Abstract

Formation of the vascular system requires differentiation and patterning of endothelial and smooth muscle cells (SMCs). Although much attention has focused on development of the vascular endothelial network, the mechanisms that control vascular SMC development are largely unknown. Myocardin is a smooth and cardiac muscle-specific transcriptional coactivator of serum response factor, a ubiquitous transcription factor implicated in smooth muscle gene expression. When expressed ectopically in nonmuscle cells, myocardin can induce smooth muscle differentiation by its association with serum response factor. Here we report that mouse embryos homozygous for a myocardin loss-of-function mutation die by embryonic day 10.5 and show no evidence of vascular SMC differentiation. Myocardin is the only transcription factor known to be necessary and sufficient for vascular SMC differentiation.

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.
