The Involution of the Ageing Human Thymic Epithelium is Independent of Puberty: A Morphometric Study

STEINMANN, G. G., KLAUS, B., MÜLLER‐HERMELINK, H.‐K.·1985·Scandinavian Journal of Immunology

Abstract

One hundred and thiriy‐six thymuses completely removed; il autopsy from persons suffering a sudden death were examined by stereological and morphomelrical meihods. Adding biopsy material from immunologically healthy cardiac patients we obtained relative volumes from 204 persons ranging in age from 1 month to 107 years. The size of the human thymus remains unchanged during ageing under normal physiological conditions (median: 19.5cm 3). Individual maximum size (range: 5‐70 cm 3) is reached in the first year of life. Early histological changes are in the enlargement of the peri vascular space, the Hassall's hodies, and the connective tissue. This begins in the first year of life, reaches a maximum from 10 to 25 years, then declines again. Adipose tissue replaces the lymphocytic pcrivascular space and the connective tissue only. This occurs extensively after the age of 15 years. When defined by the silver impregnation technique, the volumes of the thymic epithelium (cortex and medulla), show a continuous involution from the first year to the end of life. The curve can be approximated to simple negative logarithmic functions The velocity and nature of involution of the thymic epithelium do not change under the influence of the changing hormonal balance due to puberty. Since important thymic functions (T lymphopoiesis and T‐cell differentiation are located in the epithelial space. Ihe age‐related involution of the human thymlis is not related to puberty.

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.
