3D Cellular Block
Net Mold Technology
Fabricate ３D Cell Block in simple procedure without bioprinter.
Net Mold Process
Culture Cells in assembled "Net" to help cell to fuse each other.
Some Cell types have nature to adhere to each other. Net Mold is a device to help cells to adhere each others and become a Cell Block.
Net Mold an assembled "Net" which has cavity to hold cell spheroids within. As Cell spheroids are trapped by net, media will have access to cells through net opening, while spheroids are fuse together and become one large Cell Block.
Unlike conventional 3D bioprinters that use bio-inks (gels containing cells, etc.) which block cell-to cell direct fusion, cells adhere directly each others in Net Mold.
3D cell blocks by the Net Mold method are strong enough to suture and also produce many kind of cytokines such as TGF-B1.
Net Mold is effective for human, animals and plants as long as it is an adhesive cell.

Step 1: Prepare spheroids
Thousands of spheroids can be produced at once by Dimple Plate
Spheroids are "intermediate materials", so any shape can be used as long as they can be trapped by the net.
Step 2: Feed Spheroid into Net Mold
Pipette the spheroid into the net mold cavity.
After feeding, incubate in the medium for about 3 weeks.
Step 3: Remove the Net
During the culture, cell secrete collagen which is essential for fusion.
Spheroids fuse together in Net Mold cavity and they become one Cell Block.
The cell block is strong enough to be handled with tweezers and sutured.
We will make cell blocks using cells and media provided from customers.
Fibroblasts and MSCs are standard, but please contact us for other cell types.

A Net Mold-based Method of Biomaterial-free Three-Dimensional Cardiac Tissue Creation. Bai, Y., Yeung, E., Lui, C., Ong, C.S., Pitaktong, I., Huang, C., Inoue, T., Matsushita, H., Ma, C. and Hibino, N. (2018). Tissue engineering. Part C, Methods (2019).
Comparative study that demonstrates the relative effectiveness of biomaterial-free cardiac tissues created using TissueByNet NETT mold vs. traditional methods using gel mold (bioscaffold)-created tissues. By showing how net molds can produce high-functioning cardiac tissue without the drawbacks of incorporating foreign scaffolding material, it demonstrates its potential as a a reproducible and cost-effective method to treat heart failure in the future.
A Net Mold-based Method of Scaffold-free Three-Dimensional Cardiac Tissue Creation. Bai, Y., Yeung, E., Lui, C., Ong, C. S., Pitaktong, I., Huang, C., ... & Hibino, N. (2018). JoVE (Journal of Visualized Experiments) 138 (2018): e58252.
Protocol for TissueByNet NETT-based method of creating three-dimensional cardiac tissues without additional biomaterial scaffolds. The demonstrated advantages of this method may lend to the ability to create larger, more robust and high-functioning cardiac tissues free of foreign scaffolding material.
