Microfabricated blood vessels undergo neoangiogenesis

The greatest ambition and promise of tissue engineering is to manufacture human organs. Before “made-to-measure” tissues can become a reality [1], [2], [3], however, three-dimensional tissues must be reconstructed and characterized. The current inability to manufacture operational vasculature has limited the growth of engineered tissues. Here, free-standing, small diameter blood vessels with organized cell layers that recapitulate normal...
