Abstract

The performance of implantable biomedical devices is impeded by the foreign-body reaction, which results in formation of a dense collagenous capsule that blocks mass transport and/or electric communication between the implant and the body. No known materials or coatings can completely prevent capsule formation. Here we demonstrate that ultra-low-fouling zwitterionic hydrogels can resist the formation of a capsule for at least 3 months after subcutaneous implantation in mice. Zwitterionic hydrogels also promote angiogenesis in surrounding tissue, perhaps owing to the presence of macrophages exhibiting phenotypes associated with anti-inflammatory, pro-healing functions. Thus, zwitterionic hydrogels may be useful in a broad range of applications, including generation of biocompatible implantable medical devices and tissue scaffolds.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • During the first week PCBMA attracted fewer inflammatory cells and after three months displayed minimum FBC formation with increased blood-vessel density around the implant compared to PHEMA implants.

    “During the first week PCBMA attracted fewer inflammatory cells and after three months displayed minimum FBC formation with increased blood‐vessel density around the implant compared to PHEMA implants.”
  • Hydrogels loaded with ultralow-fouling zwitterionic ions have shown to completely negate in vivo capsule formation of FBR for at least 3 months while promoting angiogenesis in surrounding microenvironment.

    “Hydrogels loaded with ultralow‐fouling zwitterionic ions have already shown to completely negate the in vivo capsule formation of the FBR for a period of at least 3 months while also promoting angiogenesis in the surrounding microenvironment.[ 207 ]”
  • Low-fouling materials prevent FBR-triggering non-specific protein adsorption.

    “Certain features of material chemistry can also be exploited to beneficially influence FBR, such as the use of low-fouling materials which prevent FBR-triggering non-specific protein adsorption (Figure 1) (Zhang et al., 2013; Xie et al., 2018).”

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.
