CHAPTER 17 ONTOGENY OF THE IMMUNE SYSTEM
... In normal human adults, the generation of all cells of the hematopoietic system, with one important exception, is restricted to the bone marrow. We’ve already discussed this exception in Chapter 13; while B-cells (and most other blood cells) are produced within the bone marrow, mature T-cells are pr ...

Dendritic cells and macrophages involved in the innate response migrate to lymphoid tissue where they present antigen in association with MHC, this is why they are called antigen presenting cells (APCs).
