From: Expansion, isolation and first characterization of bovine Th17 lymphocytes
Schematic representation of the procedure used for the isolation and expansion of Th17 cells. CD4+ cells were isolated from PBMC by magnetic sorting, expanded in a culture medium without serum in the presence of polarizing cytokines and TCR-stimulation, activated, labelled for surface IL-17A and sorted by flow cytometry. The sorted cells were expanded and maintained in culture for several weeks. The indicated timeline is kept in all the figures to make it clear at which step cells were assayed. Concentrations of cytokines were 10 ng/mL (IL-2), 40 ng/mL (IL-6) and 2 ng/mL (TGF-β1). D: day; CSA: cytokine secretion assay; CSS: cytokine surface staining. α-: antibody anti-.
