Method for evaluation of cultured cells, and method for screening of biomarker

摘要

Disclosed are novel means by which evaluation of cultured cells and screening of biomarkers can be attained without consuming the cultured cells. A method for evaluating cultured cells according to the present invention comprises culturing cells in a serum-free medium, and measuring at least one nucleic acid released from the cells into the culture medium. A method for screening of a biomarker according to the present invention comprises culturing cells in a serum-free medium, and measuring a nucleic acid(s) released from the cells into the culture medium. Nucleic acid used as an indicator is e.g. microRNA.
