Abstract

Adeno-associated virus (AAV) vectors are proving to be remarkably successful for in vivo gene delivery. Based upon reports of abundant AAV in the human marrow, we tested CD34(+) hematopoietic stem cells for the presence of natural AAV. Here, we report for the first time, the presence of novel AAV variants in healthy CD34(+) human peripheral blood stem cells. The majority of healthy peripheral blood stem cell donors were found to harbor AAV in their CD34(+) cells. Every AAV isolated from CD34(+) cells mapped to AAV Clade F. Gene transfer vectors derived from these novel AAVs efficiently underwent entry and postentry processing in human cord blood stem cells and supported stable gene transfer into long-term, in vivo engrafting human HSCs significantly better than other serotypes. AAVHSC-transduced human CD34(+) cells engrafted in vivo and gave rise to differentiated transgene-expressing progeny. Importantly, gene-marked CD34(+) stem cells persisted long term in xenograft recipients, indicating transduction of primitive progenitors. Notably, correlation of structure with function permitted identification of potential capsid components important for HSC transduction. Thus, AAVHSCs represent a new class of genetic vectors for the manipulation of HSC genomes.

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.
