Ex vivo expanded Tregs retain cell surface phenotype and suppressive function. See Section 4 for expansion of Tregs. (A) and (B) Flow cytometry profiles show the relative levels of expression for cell surface markers of the ex vivo expanded Tregs and Tconvs. (C) Tregs (top panels) or control Tconvs (bottom panels) were co-cultured with responding PBMC at varying effector to responder ratios as detailed. Proliferation in response to anti-CD3/CD28 coated bead is denoted by CFSE dilution along the X-axis.
