TL;DR: Fibres encapsulating primary pancreatic islet cells and transplanted through a microcatheter into the subrenal capsular space of diabetic mice normalized blood glucose concentrations for about two weeks and may find use as templates for the reconstruction of fibre-shaped functional tissues that mimic muscle fibres, blood vessels or nerve networks in vivo.

TL;DR: A direct 3D cell printing system using inkjet and gelation techniques with inkjet droplets is developed, and it is found that it had good potential to construct 3D structures with multiple types of cells.

TL;DR: 3D layer-by-layer printing based on complicated image data has become possible, and several 2D and 3D structures with more complexity than before were successfully fabricated and the effectiveness of the on-demand printing mode in the fabrication of complicated 3D tissue structures was confirmed.

TL;DR: The technology to create these smooth muscle-like spring constructs enabled precise control of cellular alignment and orientation in 3D and can further serve as tissue engineering building blocks for larger organs and cellular implants used in clinical treatments.
