Figure 1From: A novel three-dimensional system to study interactions between endothelial cells and neural cells of the developing central nervous systemBrain EC attachment to neurospheres. Mouse brain EC were prepared, labelled with the fluorescent cell tracker marker (green), plated onto mouse neurospheres, and then cultured under serum-free conditions, as described in Methods. After 18 hours (A and B) and 5 days (C and D), EC adhesion to neurospheres was examined by fluorescent microscopy. Representative cultures are shown by phase (A and C) and fluorescent (B and D) images. Scale bars = 100 μm. Note that after 18 hours co-culture many fluorescent-labelled EC had attached to neurospheres and that after 5 days, many EC were still present, and were concentrated on or within neurospheres.Back to article page
