We examined expression profiles of nine genes implicated in CSC regulation: CD105, CD133, CD200, CD24, CD29, CD44, CD73, CD90 and NESTIN. Putative neural CSC markers are CD133, NESTIN, CD105 and CD44. 33 We observed significant positive correlations between 13-gene scores and all four markers in glioma samples (Fig. S4). Here, CD200 is linked to glioma.
