Dendritic cells (DC) are antigen-presenting cells that are critical for the initiation and regulation of the immune response. Several DC subtypes within mouse spleen have previously been characterised and these include the plasmacytoid (pDC), and conventional DC (cDC) of the CD8+ and CD8- subtypes. Each subtype appears to have a specialised role in the various arms of immunity and tolerance. Less clear is the process by which these DC develop from haematopoietic precursors, of the precursor stages and branch points from bone marrow (BM) stem cells to each of the peripheral DC subtypes. The research described herein had the aim of identifying and isolating some of the intermediate precursors of DC, downstream of stem cells, and determining whether these differed in the steady-state versus inflammation. Particular was given to DC of the spleen. Experiments that sought the identity of such precursors involved both i) transfer of cell fractions that contained DC precursors into steady-state or inflamed recipient mice to assess their in vivo development at later times, and ii) analysis of an in vitro culture system to question whether it reflected development of the steady-state DC subtypes.
