ABSTRACT:
Dendritic cells (DCs) are the primary antigen presenting cells during the initiation of T cell-dependent immune responses. The cells originate from the bone marrow and have been suggested to represent a distinct cell lineage. However, distinct DC precursors have not been identified in bone marrow, and mature monocytes can also give rise to DCs. The instant invention presents a distinct DC precursor among bone marrow CD34+ cells. The cells express high levels of the interleukin-3 receptor a chain and CD4 and can be uniquely identified also in blood and lymphoid tissues by this phenotype.
