Abstract

Human hematopoietic stem cells (HSCs) are commonly purified by the expression of cell surface markers such as CD34. Because cell phenotype can be altered by cell cycle progression or ex vivo culture, purification on the basis of conserved stem cell function may represent a more reliable way to isolate various stem cell populations. We have purified primitive HSCs from human umbilical cord blood (UCB) by lineage depletion (Lin-) followed by selection of cells with high aldehyde dehydrogenase (ALDH) activity. ALDHhiLin- cells contained 22.6% ± 3.0% of the Lin- population and highly coexpressed primitive HSC phenotypes (CD34+ CD38- and CD34+CD133+). In vitro hematopoietic progenitor function was enriched in the ALDHhiLin- population, compared with ALDHloLin- cells. Multilineage human hematopoietic repopulation was observed exclusively after transplantation of ALDHhiLin- cells. Direct comparison of repopulation with use of the nonobese diabetic/severe combined immunodeficient (NOD/SCID) and NOD/SCID β2 microglobulin (β2M) null models demonstrated that 10-fold greater numbers of ALDHhi-Lin- cells were needed to engraft the NOD/SCID mouse as compared with the more permissive NOD/SCID β2M null mouse, suggesting that the ALDHhiLin- population contained committed progenitors as well as primitive repopulating cells. Cell fractionation according to lineage depletion and ALDH activity provides a viable and prospective purification of HSCs on the basis of cell function rather than cell surface phenotype.

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.
