Abstract

Mesenchymal stem cells (MSCs) inhibit proliferation of allogeneic T cells and express low levels of major histocompatibility complex class I (MHCI), MHCII and vascular adhesion molecule‐1 (VCAM‐1). We investigated whether their immunosuppressive properties and low immunophenotype protect allogeneic rat MSCs against cytotoxic lysis in vitro and result in a reduced immune response in vivo. Rat MSCs were partially protected against alloantigen‐specific cytotoxic T cells in vitro. However, after treatment with IFN‐γ and IL‐1β, MSC s upregulated MHCI, MHCII and VCAM‐1, and cytotoxic lysis was significantly increased. In vivo, allogeneic T cells but not allogeneic MSCs induced upregulation of the activation markers CD 25 and CD 71 as well as downregulation of CD 62L on CD 4+ T cells from recipient rats. However, intravenous injection of allo‐MSCs in rats led to the formation of alloantibodies with the capacity to facilitate complement‐mediated lysis, although IgM levels were markedly decreased compared with animals that received T cells. The allo‐MSC induced immune response was sufficient to lead to significantly reduced survival of subsequently injected allo‐MSCs. Interestingly, no increased immunogenicity of IFN‐γ stimulated allo‐MSCs was observed in vivo. Both the loss of protection against cytotoxic lysis under inflammatory conditions and the induction of complement‐activating antibodies will likely impact the utility of allogeneic MSCs for therapeutic applications.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
