A new method to confirm the absence of human and animal serum in mesenchymal stem cell culture media.

In this study, we attempted to establish further the potential of this gene as a new marker indicative of the presence of serum in media. Using a real-time quantitative PCR gene array screening containing 84 functional genes, we verified BDKRB1 as a specific gene upregulated in the presence of serum. The expression of BDKRB1 in Ad-MSCs was induced not only by bovine serum but also by human serum. The BDKRB1 expression was induced even when Ad-MSCs was cultured with 0.1% serum in the medium. We concluded that BDKRB1 is a valuable marker to detect traces of both human and animal serum in Ad-MSCs cultures. Our study provides a new method to confirm the absence of serum in media and ensure a stable cell culture condition. PMID: 31523172 [PubMed - in process]
