Research Abstract |
We performed a stringent comparative gene expression profiling analysis to find genes preferentially expressed in the HSC population, and identified a total of 63 genes that are highly expressed in HSC among various hematopoietic cell population.In order to find HSC-specific marker we focused on genes encoding cell surface protein, and found that plexin domain containing 2 (Plxdc2) is highly expressed in CD34-c-Kit+Sca-1+Lineage-(CD34-KSL) HSC population using Plxdc2::GFP knock-in mice. Only 0.2% of whole bone marrow cells were Plxdc2+. Furthermore, Plxdc2+CD150+fraction represented only 0.01%±0.002% in whole bone marrow, suggesting that the simple combination of Plxdc2 and CD150 significantly increased HSC purity.
