Figure 3From: Comparative expression pattern of Matrix-Metalloproteinases in human glioblastoma cell-lines and primary culturesExpression analysis of MMPs in primary glioblastoma cells by semiquantitative RT-PCR. Four different primary cell cultures, derived from patients biopsies, were passaged ten times. Total RNA was isolated from passage 1 (p1), passage 5 (p5) and passage 10 (p10) and used for MMP specific semiquantitative RT-PCR, as described in Figure 1.Back to article page
