Cell-scaffold interaction is important for characterizing cell's mechanism such as differentiation or migration of cells. Therefore analyzing technique of the force exerted by a cell is required. In this research, we aim to realize high speed measurement of cellular traction force by applying the technique of existing vision-based tactile sensor. To achieve the measurement, we need to fabricate cellular...
Cell tissue construction is one of the important issues for tissue engineering, which is a key-technology in regenerative medicine. Recently, several studies have reported, the in vitro fabrication of simple cell tissues. However, organs are made of some kinds of cells and they are complex tissues. Therefore, a technology to reproduce the complex structure and biological function of the organ is needed...
This paper presents a flexible microscaffold driven by a thermal latch valve, which helps meet the necessity of engineered tissues with different structures for engineered organ assembly. Unlike the conventional approach, which normally utilizes a fixed scaffold, our flexible microscaffold offers many temporary scaffolds as needed. It consists of a 3×3 microactuator array with a diameter of 500 μm...
Assembling engineered tissues at the mesoscale into an engineered organ has specially attracted our attention since engineered organ usually has a very complex structure and cannot be fabricated simply by using a fixed scaffold. The fabrication of these composite tissues is, however, difficult since many different scaffolds are required. The flexible microsaffold, called “changeable cell culture (C...
