Abstract

Genetic manipulation of human embryonic stem cells (hESCs) is instrumental for tracing lineage commitment and to studying human development. Here we used hematopoietic-specific Wiskott-Aldrich syndrome gene (WAS)-promoter driven lentiviral vectors (LVs) to achieve highly specific gene expression in hESCs-derived hematopoietic cells. We first demonstrated that endogenous WAS gene was not expressed in undifferentiated hESCs but was evident in hemogenic progenitors (CD45(-)CD31(+)CD34(+)) and hematopoietic cells (CD45(+)). Accordingly, WAS-promoter driven LVs were unable to express the eGFP transgene in undifferentiated hESCs. eGFP(+) cells only appeared after embryoid body (EB) hematopoietic differentiation. The phenotypic analysis of the eGFP(+) cells showed marking of different subpopulations at different days of differentiation. At days 10-15, AWE LVs tag hemogenic and hematopoietic progenitors cells (CD45(-)CD31(+)CD34(dim) and CD45(+)CD31(+)CD34(dim)) emerging from hESCs and at day 22 its expression became restricted to mature hematopoietic cells (CD45(+)CD33(+)). Surprisingly, at day 10 of differentiation, the AWE vector also marked CD45(-)CD31(low/-)CD34(-) cells, a population that disappeared at later stages of differentiation. We showed that the eGFP(+)CD45(-)CD31(+) population generate 5 times more CD45(+) cells than the eGFP(-)CD45(-)CD31(+) indicating that the AWE vector was identifying a subpopulation inside the CD45(-)CD31(+) cells with higher hemogenic capacity. We also showed generation of CD45(+) cells from the eGFP(+)CD45(-)CD31(low/-)CD34(-) population but not from the eGFP(-)CD45(-)CD31(low/-)CD34(-) cells. This is, to our knowledge, the first report of a gene transfer vector which specifically labels hemogenic progenitors and hematopoietic cells emerging from hESCs. We propose the use of WAS-promoter driven LVs as a novel tool to studying human hematopoietic development.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 14 June 2012.
All research outputs
#20,159,700
of 22,668,244 outputs
Outputs from PLOS ONE
#172,674
of 193,511 outputs
Outputs of similar age
#151,291
of 167,326 outputs
Outputs of similar age from PLOS ONE
#3,524
of 3,847 outputs
Altmetric has tracked 22,668,244 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 193,511 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 15.0. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 167,326 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 3,847 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
