Three‐dimensional (3D) printers are attracting attention as a method for arranging and building cells in three dimensions. Bioprinting technology has potential in tissue engineering for the fabrication of scaffolds, cells, and tissues. However, these various printing technologies have limitations with respect to print resolution and due to the characteristics of bioink such as viscosity. We report...
In article 1701521, Mitsuru Akashi, Jürgen Groll, and co‐workers use a cell‐accumulation technique for the controlled formation of tubular structures in cellular constructs. The image is a confocal laser scanning microscopy image showing HUVECs attached to polycaprolactone scaffolds with 100 μm pores produced by melt electrowriting after 1 day of incubation.
A remaining challenge in tissue engineering approaches is the in vitro vascularization of engineered constructs or tissues. Current approaches in engineered vascularized constructs are often limited in the control of initial vascular network geometry, which is crucial to ensure full functionality of these constructs with regard to cell survival, metabolic activity, and potential differentiation ability...
