[0151] (1) Detection of proteins in domesticated serum-free medium

[0152] Acclimatization medium (CM) was prepared from serum-free medium using mouse embryonic fibroblasts (MEF cells) not activated by mitomycin treatment. Mouse embryonic fibroblasts (MEF cells) that were not activated by mitomycin treatment were seeded in a medium for MEF (DMEM medium supplemented with 10% FBS) at a cell density of about 500,000 cells / dish of 60 mm in diameter . After culturing the cells for at least 16 hours, wash with PBS (-), then wash with Essential8 medium (Invitrogen) (hereinafter, this serum-free medium will also be referred to as E8 medium), and replace the medium with the same serum-free medium.

[0153] After replacing the medium, the CO 2 Cultured in an incubator (37°C, 5% CO 2 concentration) for 24 hours, and then the culture medium was recovered to obtain the acclimatization medium.

[0154] The non-acclimated serum-free medium and the acclimatized serum-free medium were co...

Abstract

The purpose of the present invention is to provide a cell culture medium, particularly a serum-free cell culture medium, that makes it possible to raise cell growth efficiency without using feeder cells. The present invention provides a serum-free cell culture medium containing growth arrest-specific 6 (GAS6).

Description

[0001] This application is a divisional application of an application with a filing date of November 21, 2014, an application number of 201480063892.8, and an invention title of "Cell Culture Medium and a Culture Method Using It". technical field [0002] The invention relates to a cell culture medium and a method for culturing cells. Furthermore, the present invention also relates to a feeder cell that can be used in the above-mentioned culture method, and a method for evaluating a medium for culturing the cells. Background technique [0003] Recent studies have shown that human pluripotent stem cells such as human ES cells (hESCs) and human iPS cells (hiPSCs) are likely to be practically used in the field of regenerative medicine. These pluripotent stem cells have the ability to proliferate indefinitely and differentiate into various cells, and are expected to be used as therapeutic methods for intractable diseases and lifestyle-related diseases. Human pluripotent stem ce...
