Figure 1From: Application of microtechnologies for the vascularization of engineered tissuesCo-culture of fibroblasts and endothelial cells for one month in a collagen-GAG porous construct, resulting in a 3D capillary system within the biomaterial. Confocal imaging of the full thickness of the scaffold showing green fluorescent protein (GFP)-labeled endothelial cells forming vascular channels throughout the 3D structure of the biomaterial.Back to article page
