Abstract

The rate of contraction of the heart relies on proper development and function of the sinoatrial node, which consists of a small heterogeneous cell population, including Tbx3+ pacemaker cells. Here we isolated and characterized the Tbx3+ cells from Tbx3+/Venus knock-in mice. We studied electrophysiological parameters during development and found that Venus-labeled cells are genuine Tbx3+ pacemaker cells. We analyzed the transcriptomes of late fetal FACS-purified Tbx3+ sinoatrial nodal cells and Nppb-Katushka+ atrial and ventricular chamber cardiomyocytes, and identified a sinoatrial node-enriched gene program including key nodal transcription factors, BMP-signaling, and Smoc2, which disruption in mice did not affect heart rhythm. We also obtained the transcriptomes of the sinoatrial node region, including pacemaker and other cell types, and right atrium of human fetuses, and found a gene program including TBX3, SHOX2, ISL1, HOX family members, and BMP- and NOTCH-signaling components conserved between human and mouse. We conclude that a conserved gene program characterizes the sinoatrial node region and that the Tbx3+/Venus allele provides a reliable tool to visualize the sinoatrial node and to study its development and function.

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

  • The Tbx3-Venus reporter system is validated.

    “To visualize the activity of the murine Tbx3 promoter at the protein level, we used a validated Tbx3-Venus (Tbx3tm1(Venus)Vmc) [11, 42–47] reporter system (Fig. 2a).”

    From TBX3 is dynamically expressed in pancreatic organogenesis and fine-tunes regeneration (2023) · cites this paper as [43]

    The supplied passages contain bibliographic metadata but no discussion of a Tbx3-Venus reporter. Searches of the indexed copy for Tbx3-Venus, its allele designation, and reporter validation returned no relevant passage, so this copy does not establish whether the system was validated.

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.
