干细胞免疫表型鉴定问题，请教！

间充质干细胞在鉴定时要CD90\CD73\CD105高表达，那这三个必须都高表达呢？

To identify MSC,we propose that cells should express CD105 (known as endoglin and originally recognized by the MAb SH2),CD73 (known as ecto 5' nucleotidase and originally recognized by the MAb SH3 and SH4) and CD90 (also known as Thy-1).2 Y& l; R* a; ?1 L3 k9 w

/ T8 I2 _" |4 QCD-90 plays a role in cell-cell or cell-ligand interactions during synaptogenesis and other events in the brain Thy-1 is the designation for a major cell surface glycoprotein characteristic to T cells,. The Thy-1 glycoproteins are constituents of thymocytes and neurons and probably are involved in cell-cell interactions. Human Thy-1 homolog maps to chromosome 11 because that is where T3D is found, in the mouse T3D and Thy-1 map to chromosome 9 along with certain other loci that are on human 11q.

CD73 is a cell surface enzyme of the purine catabolic pathway that catalyzes the breakdown of AMP to adenosine.
