Abstract. In endochondral bone development, bone-forming osteoblasts and bone marrow stromal cells have dual origins in the fetal cartilage and its surrounding perichondrium. However, how early ...As with all hematopoietic lineages, T cells originate from self-renewing hematopoietic stem cells that reside in the bone marrow during steady-state postnatal life. However, unlike other major lineages, commitment to a specific T-cell program does not occur in the marrow, but rather begins only after seeding of …
