Abstract

In recognition of the enormous potential of immunotherapies against cancer, research into the interactions between tumor and immune cells has accelerated, leading to the recent FDA approval of several drugs that reduce cancer progression. Numerous cellular and molecular interactions have been identified by which immune cells can intervene in the metastatic cascade, leading to the development of several in vivo and in vitro model systems that can recapitulate these processes. Among these, microfluidic technologies hold many advantages in terms of their unique ability to capture the essential features of multiple cell type interactions in three-dimensions while allowing tight control of the microenvironment and real-time monitoring. Here, we review current assays and discuss the development of new microfluidic technologies for immunotherapy.

      The Results (Cell morphological observations; page unavailable) show a macrophage migrating toward bladder cancer cells in the microfluidic device, and the Results (Arg-1 expression in macrophages; page unavailable) report increased Arg-1 expression. Neither passage establishes that cancer cells promoted macrophage proliferation; migration and activation are different outcomes. (LLM, conf=0.85)

      In “Evidence of clinical activity for PD1 blockade” (page unavailable), the review describes promising tumour regressions and clinical responses in patients with melanoma and renal cancer, including patients with metastatic tumours. It does not establish that immunotherapy reduced the occurrence or spread of metastases, as distinct from treating existing cancer. (LLM, conf=0.82)

    Macrophages in co-culture expressed more Arginine-1, analogous to macrophage activation in the tumor microenvironment.

      The Abstract and Results (‘Making up the experiment for data-drive’; page unavailable) describe co-culturing melanoma cells with mouse splenocytes and analyzing cell migration. Searches for Arginine-1, macrophage expression, and activation found no passage reporting increased Arginine-1 in co-cultured macrophages or comparing that response with activation in the tumor microenvironment.

    Cancer cells communicate with their microenvironment, specifically with organ-specific cells, resulting in organ-selectivity in metastasis.

      The Introduction (page unavailable) invokes the seed-and-soil hypothesis to explain why tumors metastasize to particular organs. The Discussion (page unavailable) supports a narrower finding: breast cancer cells alter the brain microenvironment, which contributes to metastatic progression. The paper does not establish that communication with organ-specific cells causes organ selectivity across metastases. (LLM, conf=0.84)

    Interpretationcitation

    Microvascular networks are a dramatic improvement over previous 2D extravasation models such as Boyden Transwell-chambers because transwells do not allow dynamic high-resolution single-cell imaging and microvascular networks better replicate 3D vessel architecture and endothelial barrier function.

    “These µVNs represent a dramatic improvement over previous 2D extravasation models such as Boyden Transwell-chambers that consist of ECs seeded onto a permeable membrane inserted in a well-plate, since transwells do not allow for dynamic high resolution single cell imaging due to the long distance of the insert from the objective.”

    Intravital imaging requires specialized expertise and equipment, and high image resolution is harder in some visceral organs because of their depth.

    “While intravital imaging has proven extremely useful in the study of metastasis[6–7], it requires specialized expertise and equipment, and high image resolution is harder to attain in some visceral organs due to the depth of their location.”

      The Results section ('Platelet-Derived TGFβ1 is Necessary for Metastasis In Vivo') reports tumor cells associated with platelets in blood vessels and evidence that platelet-derived TGFβ1 aids extravasation.

      The Introduction (page unavailable) describes platelets shielding tumor cells from natural-killer-cell lysis, and the Discussion reports that platelet–tumor-cell signaling promotes metastatic seeding.

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.

Claims read under definition version 3 (extract-v3) on 2026-09-28.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-09-28.

Cited sources are checked by gpt-6-sol.

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.
