Fig. 1From: Effects on and transfer across the blood-brain barrier in vitro—Comparison of organic and inorganic mercury speciesCytotoxicity of MeHgCl (a), thiomersal (b) and HgCl2 (c) in PBCECs after 72 h incubation. Cytotoxicity was determined by a decrease of the lysosomal integrity measured by neutral red uptake. PBCECs were cultivated in rat tail collagen-coated 96 well culture plates under the same conditions as the cells seeded on Transwell® filter inserts. Shown are mean values of at least 3 independent determinations with 6 replicates + SDBack to article page
