Stem cells bearing an FGF receptor on the cell surface
First Claim
1. A composition comprising a physiologically acceptable medium and human stem cells, wherein greater than 20% of said cells are human stem cells characterized as FGFR+ and also having another indicator of a primitive state, with the proviso that said human stem cells are not embryonic stem cells.

Abstract
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 as TIE-1+, TEK+, CD31+, VE-Cadherin+ or VEGFR+ or indicative of stromal cells, such as STRO-1+.

23. A cellular composition comprising a substantially homogeneous population of cultured human stem cells displaying a phenotype of FGFR+ and another phenotype indicative of a primitive state, which cells are capable of giving rise to cells selected from the group consisting of endothelial cells, stromal cells and hematopoietic cells, with the proviso that said cells are not embryonic stem cells.
