Abstract

The mesenchymal stromal cells ( MSCs ) have become of great interest for cell therapy because of their potential to differentiate and replenish specialized tissues . Can be isolated from diverse tissues, but the umbilical cord matrix (UCM) is a promising source of MSCs for clinical applications , because the cord is usually discarded and its collection is non- invasive . However, the number of MSCs isolated from a single cord blood unit is restricted and the need for expansion is essential to achieve cell numbers adequate for a therapeutic application. The cell expansion using bioreactor technology offers the right tools to develop and optimize a culture system at low cost , with monitoring and control of the cultivation parameters , for the expansion of human MSCs quickly , safely and effectively . Furthermore, the use of reagents with undefined compositions and components derived from animals such as fetal bovine serum ( FBS ) introducing into the culture medium high concentrations of proteins that may be allergenic / immunogenic and increase the risk of contamination affecting the use of MSCs for therapeutic purposes. Thus, although widely used to supplement the culture media, such components must be replaced with serum/xeno free media. In this context , the main objective is to establish an efficient bioprocess expansion of MSCs derived from umbilical cord in bioreactors under conditions of serum/xeno-free culture, both in terms of growth and for cell recovery.
