In Vitro Differentiation of T Cells: From Human Embryonic Stem Cells and Induced Pluripotent Stem Cells

In this chapter, we describe a protocol for hematopoietic differentiation of human pluripotent stem cells (PSCs), including embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) derived from non-T cells, followed by the differentiation of the T-cell lineage. Derivation of T cells from PSCs involves three steps: induction of PSCs to hematopoietic progenitor cells (HPCs), differentiation of HPCs into progenitor T cells, and maturation of progenitor T cells into mature T cells (CD8 single-positive (SP) or CD4 SP).
