In this study, new artificial dura-mater models were developed using a multilayered structure of a rubber material (represent an elastic component of a dura-mater) and a fiber sheet (represent fiber component of a dura-mater). The artificial dura-mat

Without perfusable vascular networks, 3-D tissues populated with cells cannot maintain a living condition. To construct 3-D tissues, a well-organized vascular network is required. In this article, a method for constructing a hepatic-lobule-like vascu

Confluent cultured cells on a temperature-responsive culture dish can be harvested as an intact cell sheet by decreasing temperature below 32°C. A three-dimensional (3-D) tissue can be fabricated by the layering of cell sheets. A resulting 3-D multi
