Collagen matrix promotes reorganization of pancreatic endocrine cell monolayers into islet-like organoids.
Open accessAbstract
To evaluate the capacity of pancreatic endocrine cells to reassociate in vitro according to the characteristic topographical pattern observed in the islets of Langerhans in situ, we cultured cells dissociated from neonatal rat pancreas within a three-dimensional collagen matrix. Cell monolayers grown on the surface of collagen gels were covered with a second layer of collagen. This induced the monolayers of endocrine cells to reorganize into smooth-contoured, three-dimensional aggregates, in which non-B cells (identified by electron microscopy and immunofluorescence) had a preferential distribution at the periphery, whereas B cells were concentrated in a central position. These results show that cultured pancreatic endocrine cells have the capacity to reassociate into islet-like organoids in vitro, and that collagen matrices may have a permissive effect on the expression of this potential.

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.
