The present invention provides a culture method of cells and/or tissues including culturing cells and/or tissues in a suspended state by using a medium composition wherein indeterminate structures are formed in a liquid medium, the structures are uniformly dispersed in the solution and substantially retain the cells and/or tissues without substantially increasing the viscosity of the solution, thus affording an effect of preventing sedimentation thereof, and the like.

Culture medium composition and method of culturing cell or tissue using thereof

This is to provide a coating film having a function of inhibiting adhesion of a biological substance, a method for manufacturing the coating film, a copolymer obtainable by polymerizing a specific monomer mixture, a composition for forming a coating film having a specific composition, a method for manufacturing a varnish containing a copolymer to be used as a raw material of the composition for forming a coating film which is used for forming said film, and a sol for forming the coating film. In particular, this is to provide a coating film obtained by the method comprising a process of applying a composition for forming a coating film which comprises a copolymer comprising a recurring unit containing an organic group of the formula (a) and a recurring unit containing an organic group of the formula (b) and a solvent onto a substrate; and a process of drying at a temperature of &#x2212;200&#xb0; C. to 200&#xb0; C. (wherein U, U, U, Uand U, and Anare as defined in the present specification and the claims). 

Ion complex material having function of inhibiting adhesion of biological substance and method for manufacturing the same

The invention provides a medium additive, medium composition and a culture method and the like, capable of efficiently culturing cells or tissues in a well dispersed state, and further, permitting cell image analysis of the cells or tissues. The medium additive or medium composition contains agar, which preferably is a low molecular weight agar having a weight average molecular weight of 10,000-60,000. Using same, cells or tissues can be cultured in a well-dispersed state in a medium, and a proliferation promoting effect for the cells or tissues can also be obtained. In addition, the cells can be cultured in any of a floating state and a precipitated state by adjusting the concentration of the aforementioned agar.
