MEANS AND METHODS FOR DETERMINING MESENCHYMAL STROMAL CELL PROPERTIES.

Espacenet Family 69630203

Abstract

The invention relates to means and method for testing mesenchymal stromal cells (MSC) to determine the quality, potency and/or capacity to inhibit an immune response, such as inhibit proliferation of target cells such as T-cells, B-cells, NK cells and other immune cells and/or monocyte/macrophage polarization resulting in direct immune suppression through the production of soluble mediators and induction of T Regs. Such methods may comprise providing MSC; culturing said MSC in the presence and in the absence of one or more cytokines selected from: interleukin (IL)17A, lL-1β, oncostatin M (OSM), interferon γ (IFN-γ), tumor necrosis factor α (TNF-α), IL-13 and IL-4; contacting said MSC with binding molecules that hind to an MSC -specific marker and one or more selected from: the extracellular markers CD54, CD274, human leukocyte antigen (HLA)-DR, the intracellular markers cyclo oxygenase-2 (COX-2) and indoleamine-pyrrole 2,3-dioxygenase (IDO). Such method may further comprise determining said quality, potency and/or capacity to inhibit on the basis of the expression of said MSC- specific marker and the fold increase of the expression of said one or more of CD54, CD274, HLA-DR, COX-2 and IDO markers in response to said one or more cytokínes. The invention further provides cell banks, kits useful in and for methods of treatment using the tested MSC.
