In vitro vascularized liver and tumor tissue microenvironments on a chip for dynamic determination of nanoparticle transport and toxicity
Open accessAbstract
This paper presents the development of a vascularized breast tumor and healthy or tumorigenic liver microenvironments‐on‐a‐chip connected in series. This is the first description of a vascularized multi tissue‐on‐a‐chip microenvironment for modeling cancerous breast and cancerous/healthy liver microenvironments, to allow for the study of dynamic and spatial transport of particles. This device enables the dynamic determination of vessel permeability, the measurement of drug and nanoparticle transport, and the assessment of the associated efficacy and toxicity to the liver. The platform is utilized to determine the effect of particle size on the spatiotemporal diffusion of particles through each microenvironment, both independently and in response to the circulation of particles in varying sequences of microenvironments. The results show that when breast cancer cells were cultured in the microenvironments they had a 2.62‐fold higher vessel porosity relative to vessels within healthy liver microenvironments. Hence, the permeability of the tumor microenvironment increased by 2.35‐ and 2.77‐fold compared with a healthy liver for small and large particles, respectively. The extracellular matrix accumulation rate of larger particles was 2.57‐fold lower than smaller particles in a healthy liver. However, the accumulation rate was 5.57‐fold greater in the breast tumor microenvironment. These results are in agreement with comparable in vivo studies. Ultimately, the platform could be utilized to determine the impact of the tissue or tumor microenvironment, or drug and nanoparticle properties, on transport, efficacy, selectivity, and toxicity in a dynamic, and high‐throughput manner for use in treatment optimization.

Vessels in the breast tumor compartments were 2.62-fold more permeable to NPs than were vessels surrounded by healthy tissues.
“For example, vessels in the breast tumor compartments were 2.62-fold more permeable to NPs than were vessels surrounded by healthy tissues.”
From The Tumor-on-Chip: Recent Advances in the Development of Microfluidic Systems to Recapitulate the Physiology of Solid Tumors (2019) · cites this paper as [55]
The Abstract reports that vessels in breast tumor microenvironments had 2.62-fold higher porosity than vessels in healthy liver microenvironments, not 2.62-fold higher nanoparticle permeability. It reports particle-size-dependent permeability increases of 2.35- and 2.77-fold instead. The claim captures the direction of the difference but assigns the porosity figure to permeability.

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.
