Fig. 2From: Microfluidic in vitro brain endothelial monolayer model to evaluate cell-penetrating peptidesThe result images of microfluidic brain endothelial monolayer model at day 4. Phase images of brain endothelial cells in the microfluidic device at the bottom view (a) and the fluorescence images of them at the top, front and side view (b) were shown. The nucleus (blue), F-actin (red) and VE-cadherin (green) of brain endothelial cells in the microfluidic device was stained (scale bar = 50μm)Back to article page
