Introduction to Mebiol® Gel

Hydrogels are a diverse class of polymeric materials characterized by their network-like structure and high water content. Hydrogels of many kinds have found a wide variety of applications in medicine and life science research weighted towards, but not at all limited to three-dimensional cell culture, tissue engineering, and drug delivery. Properties highly favorable to cell culture and tissue engineering applications prompted the commercialization of Mebiol® Gel, a copolymer of poly(N-isopropylacrylamide) and poly(ethylene glycol) (PNIPAAm-PEG) for research purposes in the early 2000's.

Mebiol® Gel's defining feature, in contrast to other commercially available hydrogels, is its temperature reversible sol-gel transition. When cooled, Mebiol® Gel is a sol (handles like a liquid) but becomes a rigid hydrogel at higher temperatures. In practice, this means extremely easy cell handling. Cultures are seeded into cooled Mebiol® Gel and recovered conveniently by cooling the culture vessel and centrifugation. In the gel state, the highly lipophylic environment of the Mebiol® Gel presents an efficient niche for cell proliferation, cell communication, gas and mass exchange, and protection of cells and tissue from shear forces.

Application Examples

1) Culture of primary cancer cells in Mebiol Gel
Selective growth of only primary cancer cells from human cancerous tissue in Mebiol Gel (courtesy Dr. S. Kubota, Dept. of General Surgery, St. Marianna University School of Medicine). This technology enables the characterization of patient-derived primary cancer cells and therefore enabling the evaluation of primary cells for chemosensitivity, malignancy, metastasis activity and other parameters that might influence patient therapy.
Human colon cancerous tissue was cultured in Mebiol® Gel for 10 days. Only primary cancer cells proliferate from the tissue in Mebiol Gel. Fibroblasts growth in Mebiol® Gel is suppresed whereas In collagen and many other 3D gel culture matrices, fibroblasts overgrow and prevent proliferation of primary cancer cells.
2) Stem Cell Culture

Dynamic Viscoelastic Property of Mebiol® Gel

 
Temperature dependence of the dynamic moduli of the aqueous solution of Mebiol® Gel at a concentration of 10 wt% in distilled water. Storage modulus (G', solid lines) and loss modulus (G'', broken lines) were measured on heating (closed symbols) and cooling (open symbols) at the oscillatory frequency of 1 Hz.
