Figure 6. BIRC5, CD99 and ERBB2 expression of human glioblastoma cell lines and primary glioblastoma cells by Western blot.

All cells were HLA-A2 positive. The U87 and U251 cell lines and primary cells positively expressed ERBB2, BIRC5 and CD99. The U343 cell line positively expressed BIRC5 and CD99. (Lane 1: U87 cell line, Lane 2: U251 cell line, Lane 3: U343 cell line, Lane 4: Primary glioblastoma cells).
