IGFBP7 and astrocytoma (excluding glioblastoma): The results showed that most of the astrocytoma subclusters had a higher percentage of G1 cell cycle, in addition, C0 IGFBP7+ Glioma cells and C4 MX1+ Glioma cells had a higher percentage of Group IV, suggesting that the malignant degree of cells in these two subclusters might be higher.
