Artificial cell tissue (3D cell co-culture system)

Summary
Uniform micro-sized gel spheres encapsulating cells were first formed by using a microchannel. Then, microbeads which have stratified 3D-structure consisting of several types of cells were formed by seeding the cells over the spheres.

Artificial Blood Vessel

Summary
The inventors have succeeded in producing a three-dimensional hollow tubular artificial blood vessel having vascular endothelial cells and vascular smooth muscle cells.The present invention enables an artificial blood-vessel-like flow pass to be constructed inside a three-dimensional cell and tissue culture.  In such a structure, a culture medium and blood can be circulated, and the three-dimensional cell culture can be maintained in a condition similar to in vivo conditions.

Production method of in vitro neural network

Summary
Neural network can be efficiently produced  by culturing neurons in spheroids that are placed closely to one another. This network of neuron-containing-spheroids can be transferred onto living brain tissues; thus it may be applied to neural regenerative medicine.
