Stem cells bearing an FGF receptor on the cell surface

   
   

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.sup.+, CD34.sup.- lin.sup.-, Thy-1.sup.+, AC133.sup.+ or c-kit.sup.+. 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.sup.+, TEK.sup.+, CD31.sup.+, VE-Cadherin.sup.+ or VEGFR.sup.+ or indicative of stromal cells, such as STRO-1.sup.+.

Uma composição de pilhas de haste pluripotent substancialmente purified é positiva ambos para o receptor do fator do crescimento do fibroblast (FGFR) e um phenotype indicativo de um estado primitivo, tal como CD34.sup.+, de CD34.sup. - lin.sup. -, Thy-1.sup.+, AC133.sup.+ ou c-kit.sup.+. O estado de ser uma pilha de haste embryonic é também um phenotype indicativo de um estado primitivo. Esta população pode mais mais ser definida pelas subpopulações disso que têm um outro indicative do marcador thereon de pilhas endothelial, tais como TIE-1.sup.+, TEK.sup.+, CD31.sup.+, VE-Cadherin.sup.+ ou VEGFR.sup.+ ou indicative de pilhas stromal, tais como STRO-1.sup.+.
