épreuve biologique - test de potency

Mesenchymal stem cell (MSC) potency assessment is an essential step to establish the cell quality prior to their therapeutic application, and, as such, it is a regulatory requirement. For this purpose, ECELLFrance has developed standards for potency tests and safety controls on cultured MSC from bone marrow (BM-MSC) and adipose tissue (ASC).

ECELLFrance’s QC/potency platform is located in Toulouse. It is a key facility downstream of cell production for safety and quality assessment of the cells.

The service offering consists in two QC/potency packages (level 1 or 2) to choose from, based on the cell therapeutic applications and the aims of the project. Customized QC/potency assays may also be implemented when appropriate. The QC/potency options are discussed with the project carriers following their application. Key QC/potency offering is summarized below.


The platform has a high expertise of MSC/ASC allowing to a personalized service by a team of specialists (experience in over 20 national and European clinical trial programs in cell therapy using MSC).
