Abstract:
T cells developing in the thymus are ultimately derived from bone marrow (BM) hematopoietic stem cells (HSCs). An understanding of the developmental steps between HSCs and T cells is important for gaining insight into cancers of the T lineage, improving T cell reconstitution after BM transplantation, and also to help ameliorate immunological defects in aging. In this article, we summarize our current understanding of the inter-related fields of early T cell development and thymic aging, and briefly discuss major unresolved questions in this field.
