Cell therapeutic products such as stem cells require in vitro cultivation. This inevitably could lead to various issues, e.g. changes in biological attributes, biosafety, exogenous contamination, cross-contamination, etc. These issues could significantly influence the progress and success of the production from beginning to the end. Stem cell overall quality is determined by the  basic biological attributes, microbiological safety, biological safety, and biological efficacy. In Canvest Bio, we work with each client to provide necessary tests to meet the production and government filing requirements.
