Lymphoid precursor IL-7Ra + Pax-5 + SCL - c-kit + Lymphoid Myeloid precursor HSC DC - precursors DC IL-7Ra - Pax-5 - SCL + c-kit + IL-7Ra - Pax-5 - SCL - c-kit - Myeloid precursor IL-7Ra - Pax-5 - SCL + c-kit + Mouse DC differentiation model DC may be generated by two separate differentiation routes from either lymphoid- or myeloid-committed precursors, or alternatively by a common DC differentiation pathway through DC-precursors, independently from lymphoid and myeloid progenitors. The biological significance of this model, including the analysis of the differential expression of IL-7Ra, Pax-5, SCL and c-kit by DC-precursors, is discussed in the printed version of the paper.
