Abstract

Congenital heart defects are present in 8 of 1000 newborns and palliative surgical therapy has increased survival. Despite improved outcomes, many children develop reduced cardiac function and heart failure requiring transplantation. Human cardiac progenitor cell (hCPC) therapy has potential to repair the pediatric myocardium through release of reparative factors, but therapy suffers from limited hCPC retention and functionality. Decellularized cardiac extracellular matrix hydrogel (cECM) improves heart function in animals, and human trials are ongoing. In the present study, a 3D‐bioprinted patch containing cECM for delivery of pediatric hCPCs is developed. Cardiac patches are printed with bioinks composed of cECM, hCPCs, and gelatin methacrylate (GelMA). GelMA‐cECM bioinks print uniformly with a homogeneous distribution of cECM and hCPCs. hCPCs maintain >75% viability and incorporation of cECM within patches results in a 30‐fold increase in cardiogenic gene expression of hCPCs compared to hCPCs grown in pure GelMA patches. Conditioned media from GelMA‐cECM patches show increased angiogenic potential (>2‐fold) over GelMA alone, as seen by improved endothelial cell tube formation. Finally, patches are retained on rat hearts and show vascularization over 14 d in vivo. This work shows the successful bioprinting and implementation of cECM‐hCPC patches for potential use in repairing damaged myocardium.

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

  • Printing tissues composed entirely of native proteins, cells, and/or biocompatible synthetic components is possible and accessible to many laboratories.

    “The concept is gaining traction, as the ability to print tissues composed entirely of native proteins, cells and/or biocompatible synthetic components is possible and accessible to many laboratories9–17.”

    From In situ expansion, differentiation, and electromechanical coupling of human cardiac muscle in a 3D bioprinted, chambered organoid (2020) · cites this paper as [10]

    The Conclusions (page not provided) report successful bioprinting of a cardiac patch made with extracellular matrix, progenitor cells, and gelatin methacrylate. This establishes that such printing is possible, but the paper does not establish that it is accessible to many laboratories. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • 3D bioprinting can generate models replicating the heart's complex structure with chambers and large vessels using soft biomaterials.

    “Models that replicate the geometrically complex structure of the heart, harboring chambers and large vessels with soft biomaterials, can be achieved using 3D bioprinting.”

    From In situ expansion, differentiation, and electromechanical coupling of human cardiac muscle in a 3D bioprinted, chambered organoid (2020) · cites this paper as [10]

    The Introduction (page not provided) says bioprinting produces controlled 3D structures with defined biomaterial geometries. The Results and Discussion (page not provided) describe cylindrical cardiac patches, not models replicating a whole heart with chambers and large vessels. That specific anatomical claim is unsupported. (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.
