Here, we provide an optimized protocol for the isolation and cloning of the scarce T-cell entity of peripheral Vδ1+CD4+ T cells that is, as we showed recently, an extrathymic αβ T-cell progenitor. This technique allows to quantitatively isolate, clone and efficiently expand these cells in ex vivo culture.
