Figure 1From: Comparative study of four immortalized human brain capillary endothelial cell lines, hCMEC/D3, hBMEC, TY10, and BB19, and optimization of culture conditions, for an in vitro blood–brain barrier model for drug permeability studiesPhase contrast microscopy of four immortalized human brain capillary endothelial cell lines. Four endothelial cell lines were cultured in growth medium containing 20% FBS for 2 days and the representative cell morphology was imaged with a phase contrast microscope. Scale bar: 150 μm.Back to article page
