A colony (cell mass) proliferated under the undifferentiated state is obtained by using a carrier for cell culture in which two or more of a concavity having a porous body in a surface are arranged on a substrate surface in the form of a matrix, inoculating an undifferentiated cell on at least one concavity of the carrier for culture and carrying out culture.

Carrier for undifferentiated cell culture and subculture method thereof

A culture substrate made of ceramics of any one or more of titania, alumina, zirconia, yttria, and carbon is used where minute pores having a pore diameter of from 0.1 &#x3bc;m to 10 &#x3bc;m are provided at least for a place to which a cell is seeded, and an undifferentiated cell is seeded to at least one place of a surface of the culture substrate, whereby a culture substrate and a culture method for efficiently culturing the undifferentiated cell to be formed into a 3-dimensional cell block shape without causing immune rejection, and an undifferentiated cultured cell.

Culture substrate and culture method for undifferentiated cell and undifferentiated cultured cell

The present invention relates to a cell culture support for culturing mesenchymal stem cells, which includes en upper surface including a plurality of wells, in which the upper surface has a root mean square roughness Rq of 100 to 280 nm and a linear density of 1.6 to 10 per 1 &#x3bc;m length.

Cell culture support and cell culture method

The gas filter module of the invention has: a housing which has a gas inlet port at one end and a gas outlet port at another end, and which is divided into two portions in a longitudinal direction; a filter body consisting of a porous ceramics member which is loaded into the housing and through which an inflow gas passes; and a ring-like support member consisting of dense ceramics which is fittingly coupled to a step portion formed inside the housing and which is joined to the filter body. The ring-like support member is fixed via two metal O-rings to a fixing gap of the step portion of the housing.
