A graft polymer is provided, which includes a polymer backbone with a plurality of hydroxy groups, protection group modified histidine grafted onto the side of the polymer backbone, and hydrophilic polymer having terminal reactive group grafted onto the side of the polymer backbone. The graft polymer coating can be applied to metal material to form a composite material, which can be implanted into an organism to reduce adhesion problems.

Graft polymer and composite material containing the same

A surface modification method of polysaccharide, the modified polysaccharide, and a method of culturing and recovery cells using the same are provided. The surface modification method of polysaccharide comprises (a) immersing a polysaccharide material in an acid, (b) immersing the polysaccharide material in an acidic solution containing a protein, and (c) immersing the polysaccharide material in an alkaline solution containing bivalent metal ions.

A porous chamber for tissue culture in vitro. The porous chamber includes a main body made of porous biologically absorbable polymer material, comprising an inner surface surrounding a hollow cavity, the hollow cavity having an aperture opened at an upper surface of the main body, wherein the aperture is communicated with outside of the main body for seeding tissue blocks in the hollow cavity, and an upper cover passing through the upper surface of the main body to seal the aperture to prevent the tissue blocks from outflowing.

A porous matrix, preparation thereof, and methods of using the same. The porous matrix of calcium alginate is prepared using a plurality of particles containing a multivalent cation, admixing the particles with ionic cross-linked polysaccharides and water to form a mixture, introducing a cross linker to solidify the mixture, dissolving the particles of the mixture in an acid to form a porous structure, and neutralizing and cross-linking the porous structure.

Methods of producing a porous matrix for culturing and recovering cells

The present invention provides a process for producing porous polymer materials. In the present invention, a polymer material and a soluble material are mixed in their solid states. The surface of the polymer material is partially dissolved and fused by introducing a solvent. The present invention makes use of a pressure difference while introducing a non-solvent into the polymer material to solidify and resolve the solved polymer material. Then, a substantial amount of water is used to wash the inside soluble material out. Therefore, the porous polymer materials with high porosity and interconnecting pores inside the materials are produced massively and rapidly.

A cell-cultivating device includes a plurality of culture tanks and a driving device. The culture tanks communicate with each other and have culture medium inside. The driving device forces the culture medium to flow between the culture tanks so as to vertically oscillate medium levels in the culture tanks.

Highly efficient cell-cultivating device
