Abstract

We have previously shown that fetal growth restriction (FGR) during late gestation in sheep affects lung development in the near-term fetus and at 8 wk after birth. In the present study, our aim was to determine the effects of FGR on the structure of the lungs at 2 y after birth; our hypothesis was that changes observed at 8 wk after birth would persist until maturity. FGR was induced in sheep by umbilicoplacental embolization, which was maintained from 120 d until delivery at term (approximately 147 d); birth weights of FGR lambs were 41% lower than in controls. At 2 y after birth, body and lung weights were not different, but there were 28% fewer alveoli and alveoli were significantly larger than in controls; hence there was a 10% reduction in the internal surface area relative to lung volume in FGR sheep compared with controls. The lungs of FGR sheep, compared with controls, had thicker interalveolar septa as a result of increased extracellular matrix deposition; the alveolar blood-air barrier was also thicker, largely because of an 82% increase in basement membrane thickness. These changes are qualitatively similar to those observed at 8 wk. Our data show that structural alterations in the lungs induced by FGR that were apparent at 8 wk were still evident at 2 y after birth, indicating that FGR may result in permanent changes in the structure of the lungs of the offspring and may affect respiratory health and lung aging later in life.

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.
