Generation of Human Alloantigen-Specific Regulatory T Cells under Good Manufacturing Practice-Compliant Conditions for Cell Therapy

Ex Vivo Generation of Human Alloantigen-Specific Regulatory T Cells from CD4posCD25high T Cells for Immunotherapy

BACKGROUND Regulatory T cell (Treg) based immunotherapy is a potential treatment for several immune disorders. By now, this approach proved successful in preclinical animal transplantation and auto-immunity models. In these models the success of Treg based immunotherapy crucially depends on the antigen-specificity of the infused Treg population. For the human setting, information is lacking on ...

Ex Vivo Generation of Human Alloantigen-Specific Regulatory T Cells from CD4posCD25hig T Cells for Immunotherapy

Good manufacturing practice-compliant expansion of marrow-derived stem and progenitor cells for cell therapy.

Ex vivo expansion is being used to increase the number of stem and progenitor cells for autologous cell therapy. Initiation of pivotal clinical trials testing the efficacy of these cells for tissue repair has been hampered by the challenge of assuring safe and high-quality cell production. A strategy is described here for clinical-scale expansion of bone marrow (BM)-derived stem cells within a ...

Efficient generation of human alloantigen-specific CD4+ regulatory T cells from naive precursors by CD40-activated B cells.

CD4(+)CD25(+)Foxp3(+) regulatory T cells (Treg) play an important role in the induction and maintenance of immune tolerance. Although adoptive transfer of bulk populations of Treg can prevent or treat T cell-mediated inflammatory diseases and transplant allograft rejection in animal models, optimal Treg immunotherapy in humans would ideally use antigen-specific rather than polyclonal Treg for g...

Good manufacturing practice-compliant isolation and culture of human adipose- derived stem cells

Adipose-derived stem cells (ADSCs) are excellent for regenerative medicine. Like mesenchymal stem cells, ADSCs possess multi-potent differentiation capacity that enables them to differentiate into osteoblasts, chondrocytes and adipocytes, as well as trans-differentiation into other cells. ADSC transplantation has gained attention in recent years, especially in vitro expanded ADSC transplantatio...
