Eligibility of established meningioma cell lines for in-vitro analyzes of tumor fluorescence significantly differs. Fluorescence in Ben-Men 1 and primary meningioma cell lines but less in IOMM Lee cells is 5-ALA dose-dependent, encouraging in-situ trials to encounter currently discussed shortcomings of FGS in meningiomas. Fluorescence is not related to expression of FECH, ABCB6 and ABCG2.
