Celsheed Technology By utilizing a unique nano-surface design, temperature-responsive polymer (PIPAAm) has been immobilized on the surface of equipment. This allows the surface temperature to be lowered, causing the culture surface to change from hydrophobic (cell-adhesive) to hydrophilic (cell-releasing) at around 32°C, resulting in cell detachment. Without using any enzymes that can damage cells, such as trypsin, intact cells can be recovered simply by setting the equipment temperature to 20-25°C and waiting for about 10-30 minutes. ● This is the first large flask type UpCell developed for large-scale culture. ● Adhesive cells such as mesenchymal stem cells, dendritic cells, and macrophages can be recovered without trypsin treatment. ● The flask type minimizes the risk of contamination.

◆The temperature-responsive culture device UpCell for cell recovery is equipped with "grid walls" placed at 3mm intervals. ◆It has become easier to recover cultured cells in single cell/small colony form. ◆The grid wall is a new technology that prevents cells from proliferating beyond the grid by using optimized grooves on the surface of the culture dish. Cells can be recovered intact with just a short time and temperature treatment. Advantages of RepCell - It is known that trypsin significantly damages cell viability, but with RepCell, it is possible to recover cells while maintaining surface antigens and extracellular matrix. - Cell detachment using only temperature treatment The only necessary procedure for cell recovery is temperature treatment, eliminating the need for cumbersome pipetting operations associated with traditional trypsin use.

By applying our unique nano-surface design technology, we have fixed (covalently bonded) superhydrophilic polymers to the surfaces of our equipment. In addition to being superhydrophilic, this polymer creates a free water film. The double effect of "superhydrophilicity" and "free water" has achieved a level of low adhesion performance that far surpasses conventional low-adhesion equipment.

- Celsid's Technology By utilizing a unique nano-surface design, temperature-responsive polymer (PIPAAm) has been immobilized on the surface of the equipment. This allows the surface to change from hydrophobic (cell-adhesive surface) to hydrophilic (cell-releasing surface) by lowering the surface temperature around 32°C. Without using any enzymes that can damage cells, such as trypsin, intact cells can be recovered simply by setting the equipment temperature to 20-25°C and waiting for about 10-30 minutes. - Benefits 1) Easy cell recovery through temperature control. 2) Recovered cells completely retain the extracellular matrix. 3) No need for trypsin, which can harm cells. 4) Suitable for culturing tissues used in regenerative medicine research. 5) For 3D culture by stacking homo/heterogeneous cell sheets.

It is a transparent heating element made of specially processed hard glass. It improves work efficiency in clean benches for tasks such as microscope observation and media exchange using UpCell/RepCell. Temperature settings are possible from room temperature to 50°C. It is lightweight (approximately 70g) and suitable for portability. It can also be used to cover petri dishes and multi-well plates to prevent fogging during photography. Demonstrations are available. For more details, please contact us or refer to the catalog.

Features Dedicated cell sheet recovery support "CellShifter" for UpCell Utilizes a material with flexibility and water absorption suitable for cell detachment that could not be achieved with hydrophilic PVDF membranes or nitrocellulose membranes. This allows for the reliable and easy recovery of your precious cell sheets that have been carefully cultured with UpCell. The CellShifter, with the cell sheet adhered to it, boasts excellent ease of handling when transplanted directly to the host. Thanks to the specially treated material, there are almost no detached fibers. We guarantee maximum experimental results. Please take this opportunity to experience the results of years of material development.

Features of Regenerative Medicine Contract Services 1. Development and Contract Manufacturing of Cell Sheet Products We provide contract development and manufacturing services primarily for cell sheets, commissioned by pharmaceutical companies and research institutions. Our team includes clinical culture specialists certified by the Japanese Society for Regenerative Medicine, and we offer high-quality cell sheet product development and manufacturing using experienced staff in a cell culture processing facility licensed for the production of specific cell processed products. 2. Facility Management and Application Support The "Act on Securing Safety for Regenerative Medicine" stipulates the structure, equipment, and operation of cell processing, requiring each cell culture processing facility to submit notifications and applications for permits to the Minister of Health, Labour and Welfare. At CellSeed, we assist with the notification and application documentation for the manufacture of specific cell processed products, as well as the creation of necessary operational documents. Additionally, we support the necessary administrative procedures, including the preparation of consultation materials for authorities regarding applications such as clinical trial notifications. 3. Education for Cell Culture Technicians We conduct training for cell culture technicians who have no prior experience with cell sheets, covering procedures such as cell sheet culture and detachment at our cell culture facility. For more details, please contact us or refer to our catalog.
