Impaired Ability of Bone Marrow Stromal Cells to Support B-Lymphopoiesis With Age
Open accessAbstract
B-lymphopoiesis decreases with age. We studied how aging affects bone marrow stromal cells, because they provide the growth factors and cell contacts required for B-lymphopoiesis. No differences were noted in the cell-surface phenotype of young and old primary-cultured stromal cells. Fluorescence-activated cell sorter-purified stromal cells from old mice were deficient in the ability to support the proliferation of interleukin-7 (IL-7)–specific B-lymphoid cell lines. The kinetics of this response indicated that IL-7 was not immediately available from stromal cells of either age and was further delayed on aged stromal cells. The levels of IL-7 protein within stromal cells were equivalent between young and old animals, suggesting that the production of IL-7 was not altered by aging. Negligible amounts of IL-7 were found either freely secreted or in the extracellular matrix of cultures of young and old marrow. Contact between the lymphoid cells and the primary stromal cells was required for detectable proliferation, suggesting that cell contact was required for the release of IL-7. We propose that stromal cells regulate B-lymphopoiesis by limiting the amount of IL-7 available to the developing precursors. Therefore, we conclude that the age-related decrease in the function of bone marrow stromal cells is related to the impaired release of IL-7.

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.
