A developmental switch in B lymphopoiesis.
Open accessAbstract
B and T lymphocytes are generated from hematopoietic stem cells during both fetal and adult life. A critical unresolved issue is whether the differentiation pathways in lymphopoiesis are the same in fetal and adult animals or whether they differ, similar to the hemoglobin switch in erythropoiesis. We report here that a developmental switch occurs in B lymphopoiesis. We isolated "pro-B" cells (i.e., cells that have initiated, but not completed, heavy-chain gene rearrangement) from fetal and adult sources and investigated their B-cell progeny generated both in vitro and in vivo. Most of the cells from fetal liver, but few from adult bone marrow, expressed CD5. Further, fetal pro-B cells failed to generate cells expressing high levels of IgD in severe combined immunodeficiency mice, whereas adult pro-B cells gave rise to CD5-B cells bearing IgD at levels comparable to the bulk of cells in the spleen of adult mice. Thus, all committed B progenitors in fetal liver of day 16 gestation mice give rise to phenotypically distinct progeny when compared to cells at a comparable differentiation stage in the bone marrow of adult animals. We conclude that the cohort of B-lineage progenitors in early fetal development is committed to a differentiation pathway distinct from that seen in the adult.

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.
