Diminished β-cell replication contributes to reduced β-cell mass in fetal sheep with intrauterine growth restriction

Abstract

Human fetuses with severe intrauterine growth restriction (IUGR) have less pancreatic endocrine tissue and exhibit β-cell dysfunction, which may limit β-cell function in later life and contribute to their increased incidence of noninsulin-dependent diabetes mellitus. Three factors, replication, apoptosis, and neoformation, contribute to fetal β-cell mass. We studied an ovine model of IUGR to understand whether nutrient deficits lead to decreased rates of fetal pancreatic β-cell replication, increased rates of apoptosis, or lower rates of differentiation. At 90% of term gestation, IUGR fetal and pancreatic weights were 58% and 59% less than pair-fed control, respectively. We identified a selective impairment of β-cell mass compared with other pancreatic cell types in IUGR fetuses. Insulin and insulin mRNA contents were less than other pancreatic endocrine hormones in IUGR fetuses, as were pancreatic insulin positive area (42%) and β-cell mass (76%). Pancreatic β-cell apoptosis was not different between treatments. β-cell capacity for cell cycling, determined by proliferating cell nuclear antigen (PCNA) immunostaining, was not different between treatment groups. However, the percentage of β-cells actually undergoing mitosis was 72% lower in IUGR fetuses. These results indicate that in utero nutrient deficits decrease the population of pancreatic β-cells by lengthening G1, S, and G2 stages of interphase and decreasing mitosis near term. Diminished β-cell mass in IUGR infants at birth, if not adequately compensated for after birth, may contribute to insufficient insulin production in later life and, thus, a predisposition to noninsulin-dependent diabetes.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • A growth-restricted fetus has fewer insulin-producing beta cells and reduced vascularization in the pancreas, and compromised structure and maturation of the brain, lungs, and liver.

    “In addition, the pancreas has fewer insulin-producing beta cells and reduced vascularization (159, 340, 473), and the structure and maturation of the brain (142), lungs (358, 359, 424, 460) and liver (209, 474) are compromised.”

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.
