CHI3L2 and glioblastoma: Figure 8A shows that CHI3L2 is expressed in glioblastoma cell lines and a microglia cell line. It is strongly expressed in the glioblastoma cell lines U87, U251, LN229, A172 and the microglia cell line HMC3, while the expression in the glioblastoma cell lines T98G and DBTRG is weak. Figure 8B is the result of flow cytometry analysis.
