In vitro grafting of hepatic spheroids and organoids on a microfluidic vascular bed
Open accessAbstract
With recent progress in modeling liver organogenesis and regeneration, the lack of vasculature is becoming the bottleneck in progressing our ability to model human hepatic tissues in vitro. Here, we introduce a platform for routine grafting of liver and other tissues on an in vitro grown microvascular bed. The platform consists of 64 microfluidic chips patterned underneath a 384-well microtiter plate. Each chip allows the formation of a microvascular bed between two main lateral vessels by inducing angiogenesis. Chips consist of an open-top microfluidic chamber, which enables addition of a target tissue by manual or robotic pipetting. Upon grafting a liver microtissue, the microvascular bed undergoes anastomosis, resulting in a stable, perfusable vascular network. Interactions with vasculature were found in spheroids and organoids upon 7 days of co-culture with space of Disse-like architecture in between hepatocytes and endothelium. Veno-occlusive disease was induced by azathioprine exposure, leading to impeded perfusion of the vascularized spheroid. The platform holds the potential to replace animals with an in vitro alternative for routine grafting of spheroids, organoids, or (patient-derived) explants.

Liver-on-chip platforms offer advantages in maintaining hepatocyte function, promoting cell-cell and cell-matrix interactions, and enabling dynamic exposure to drugs and metabolites.
“Liver-on-chip (LoC) platforms, in particular, offer advantages in maintaining hepatocyte function, promoting cell–cell and cell–matrix interactions, and enabling dynamic exposure to drugs and metabolites in a manner more akin to the intact liver [20, 21].”
From High-throughput human microfluidic organoid-on-a-chip platform for modeling liver diseases and screening nanotherapeutics. (2026) · cites this paper as [20]
The Results sections report maintained hepatic function during co-culture, hepatocyte–endothelial contact, ECM deposition, and a perfusable vascular network. They also describe azathioprine exposure, but do not establish dynamic exposure to both drugs and metabolites or show that these interactions more closely reproduce the intact liver.

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.
