A composition of substantially purified pluripotent stem cells are positive both for fibroblast growth factor receptor (FGFR) and a phenotype indicative of a primitive state, such as CD34<+>, CD34<->lin<->, Thy-1<+>, AC133<+> or c-kit<+>. The state of being an embryonic stem cell is also a phenotype indicative of a primitive state. This population may be further defined by the subpopulations thereof which have another marker thereon indicative of endothelial cells, such a TIE-1<+>, TEK<+>, CD31<+>, VE-Cadherin<+> or VEGFR<+> or indicative of stromal cells, such as STRO-1<+>. |
