As previously reported [19], genes highly expressed in cancer stroma compared to normal stroma, such as BGN, COL1A1, COL1A2, COL5A1, FN1, NID2, COL10A, COL11A1, COL3A1, MMP2, POSTN, SPARC, DST and THBS2, produced high number of RPKM and positively correlated with the gene expression array data (Figure 6 C). This evidence concerns the gene NID2 and cancer.
