Abstract

We present a new strategy for the differentiation of embryonic stem (ES) cells into insulin-producing cells via a multi-step process without selection and induction of nestin-positive cells. During ES cell differentiation, transcript levels of genes characteristic of early and mature beta cells including Pdx1, Pax4, insulin and islet amyloid pancreatic peptide are up regulated. Islet-like clusters are characterized by expression of C-peptide, insulin and partially cytokeratin 19 as well as by ion channel activity similar to that found in embryonic beta cells. Cells of islet-like clusters show glucose-dependent insulin release at terminal stage. At an intermediate stage, nestin is partially co-expressed with C-peptide and cytokeratin 19, whereas islet-like clusters at the terminal stage are nestin-negative. We conclude that expression of nestin and cytokeratin 19 is a normal property of ES cells preceding differentiation into C-peptide/insulin-producing cells without any selection for nestin-positive phenotypes.

  • Several methods of differentiation of ES cells to hepatic and insulin-producing cells have been described, but determining the precise identity of these cells is problematic due to a lack of suitable markers.

    “While several methods of differentiation of ES cells to hepatic and insulin-producing cells have been described, determining the precise identity of these cells is problematic due to a lack of suitable markers [20-23].”

    From A systematic screen for genes expressed in definitive endoderm by Serial Analysis of Gene Expression (SAGE) (2007) · cites this paper as [22]

    The Discussion (page unavailable) describes several methods for producing insulin-positive cells from ES cells and cautions that some cells may absorb insulin from the medium rather than produce it, supporting a difficulty in identifying them. It does not discuss ES-cell differentiation into hepatic cells or attribute the identification difficulty to a lack of suitable markers. (LLM, conf=0.84)

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.
