A novel, flexible and automated manufacturing facility for cell-based health care products: Tissue Factory.

Introduction: Current production facilities for Cell-Based Health care Products (CBHPs), also referred as Advanced-Therapy Medicinal Products or Regenerative Medicine Products, are still dependent on manual work performed by skilled workers. A more robust, safer and efficient manufacturing system will be necessary to meet the expected expansion of this industrial field in the future. Thus, the 'flexible Modular Platform (fMP)' was newly designed to be a true "factory" utilizing the state-of-the-art technology to replace conventional "laboratory-like" manufacturing methods.

Corneal regeneration by transplantation of corneal epithelial cell sheets fabricated with automated cell culture system in rabbit model.

We have performed clinical applications of cell sheet-based regenerative medicine with human patients in several fields. In order to achieve the mass production of transplantable cell sheets, we have developed automated cell culture systems. Here, we report an automated robotic system utilizing a cell culture vessel, cell cartridge.

Fabrication of transplantable corneal epithelial and oral mucosal epithelial cell sheets using a novel temperature-responsive closed culture device.

Temperature-responsive culture surfaces make it possible to harvest transplantable carrier-free cell sheets. Here, we applied temperature-responsive polymer for polycarbonate surfaces with previously developed closed culture devices for an automated culture system in order to fabricate transplantable stratified epithelial cell sheets. Histological and immunohistochemical analyses and colony-forming assays revealed that corneal epithelial and oral mucosal epithelial cell sheets could be harvested with the temperature-responsive closed culture devices.

A novel closed cell culture device for fabrication of corneal epithelial cell sheets.

Automation technology for cell sheet-based tissue engineering would need to optimize the cell sheet fabrication process, stabilize cell sheet quality and reduce biological contamination risks. Biological contamination must be avoided in clinical settings. A closed culture system provides a solution for this.
