Thirty‐five (63%) out of the 56 GISTs examined stained for FGL2 (Figure 1C), whereas only two of the out of the 542 non‐GIST tumours consisting of 35 histological types stained for FGL2 (one meningioma and one schwannoma), suggesting that FGL2 expression is higher in GISTs than in most other types of human cancer (Table S5). Here, FGL2 is linked to gastrointestinal stromal tumor.
