Abstract

Inflammatory bowel disease (IBD) causes inflammation to the gastrointestinal tract. Local administration of anti‐inflammatory drugs such as 5‐aminosalicylic acid (5‐ASA) can alleviate the symptoms of IBD. The application of nanoparticles for IBD treatment in direct rectal administration showed high drug availability and treatment efficacy. However, relying on size‐dependent adsorption of smaller particles is not sufficient for making the formulation capable of targeting. Intestinal organoids can improve the functionality of the nanoparticles due to their ability to adsorb small nanoparticle inside the lumen and attach to the damaged area. In this study, intestinal organoids were used as carriers of 5‐ASA‐loaded poly(lactic‐co‐glycolic acid) nanoparticles. The nanoparticle sizes, confirmed by scanning electron microscopy, were 200–300 nm and the zeta potential were negative. The nanoparticles did not have any noticeable pernicious effect on organoid growth and viability. After mixing the nanoparticles with Matrigel and organoids, Rhodamine B loaded inside the nanoparticles was highly detected inside the organoid's lumen after 3 days by confocal fluorescent microscopy and no longer detected in the lumen after day 4. It may be attributed to the ability of the lumen to digest particles. Thus, the organoid Trojan horse system is a possible approach for delivering drugs to inflamed areas. © 2017 Wiley Periodicals, Inc. J Biomed Mater Res Part A: 106A: 876–886, 2018.

  • Growth factors can be encapsulated within nanoparticles and conjugated onto cell surfaces for controlled release.

    “these growth factors can be encapsulated within nanoparticles, and conjugated onto cell surfaces for controlled release85–88.”

    From Organoids (2022) · cites this paper as [86]

    The Introduction describes drug-loaded nanoparticles carried by cells and identifies controlled drug release as an advantage of cell-mediated delivery. But the paper studies 5-ASA-loaded nanoparticles taken into organoid lumens; it does not describe encapsulating growth factors or conjugating them onto cell surfaces. The indexed passages have section labels but no page numbers. (LLM, conf=0.83)

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.
