The discovery of iPS cells (that can differentiate into many different types of cells) as well as the development of cell encapsulation technologies (that encapsulate cells using semi-permeable membranes or gels), opened the new door to the realization of regenerative medicine/cell therapy. Along with this, there have been significant advancements in research and development of three-dimensional (3D) biological tissue construction and cell encapsulation technologies.
Ricoh has successfully developed cell-friendly inkjet printhead that allows the production of fine droplets. By applying this technology, we then enabled the uniform and high-throughput production of encapsulated cells in desired sizes, even at high volumes, without harming the cells. Additionally, by combining precise cell-dispensing technology, we are working on a realization of functional 3D human tissues.
Ricoh has been focusing on the development of new inkjet printhead and bioink for printing of living cells. These technologies enabled the development of a cell-friendly inkjet-based bio-printing technology that reduces stress on the cells.
Cell layering - Regenerative medicine × Ricoh
By leveraging our own existing printing technology, Ricoh has developed the "Bio 3D Printer" that enables cell friendly high-precision/high-throughput printing as well as the application of advanced cell encapsulation techniques. Ricoh hopes to contribute to the further development of drug discovery and regenerative medicine, including alternatives to animal testing.
