The perivascular niche regulates breast tumour dormancy
Open accessAbstract
In a significant fraction of breast cancer patients, distant metastases emerge after years or even decades of latency. How disseminated tumour cells (DTCs) are kept dormant, and what wakes them up, are fundamental problems in tumour biology. To address these questions, we used metastasis assays in mice and showed that dormant DTCs reside on microvasculature of lung, bone marrow and brain. We then engineered organotypic microvascular niches to determine whether endothelial cells directly influence breast cancer cell (BCC) growth. These models demonstrated that endothelial-derived thrombospondin-1 induces sustained BCC quiescence. This suppressive cue was lost in sprouting neovasculature; time-lapse analysis showed that sprouting vessels not only permit, but accelerate BCC outgrowth. We confirmed this surprising result in dormancy models and in zebrafish, and identified active TGF-β1 and periostin as tumour-promoting factors derived from endothelial tip cells. Our work reveals that stable microvasculature constitutes a dormant niche, whereas sprouting neovasculature sparks micrometastatic outgrowth.

The source backs part of the claim, not all of it — or backs it for a different population, condition or comparison.
In the citing paper
“Recent studies are increasingly employing microvascular networks (µVNs)[21, 23, 24], where the permeability, architecture and diameters of vessels are more similar to those found in in vivo microvascular beds (Figure 2A) [21].”

Experimental — accuracy not yet measuredThe cited source says what the claim attributes to it.
In the citing paper
“Studies have shown that dormancy can be induced by endothelial derived factors[24], thus demonstrating the need for microfluidic models that recapitulate interactions between ECs and tumor cells, using for example µVNs.”

“For example, the apparent dormancy-inducing actions of the perivascular niche noted above seem to be reversed during neo-vascularization as sprouting endothelial tip cells secrete TGF-β1 and periostin (POSTN), which can break dormancy and promote tumor cell proliferation (Ghajar et al., 2013).”

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.
