Human peripheral blood monocytes (HPBM) were cultured in the
absence of human serum and were converted into a state exhibiting a high
accessory function expressed by their ability of supporting lymphocyte
proliferation. After a prolonged culture in serum free media the monocyte
derived cells were highly viable, increased in size and developed veils and
dendritiform elongatio'l1s. Paralleling the increase in accessory function, the
cells decreased in the expression of markers typical of monocytes and
macrophages (M 0), approaching the phenotype of lymphoid dendritic cells.
We here define conditions for reproducibly generating these monocyte
derived dendritic cells (m-DC) in various serum free media. This study also
shows that acidic conditions prevent M0 development and facilitate m-DC
differentiation even under serum conditions.
