Research Abstract |
We identified a novel human myeloid progenitor population that expressed Notch-1 at a high level. These Notch-1 positive progenitors preferentially differentiated into the monocyte/dendritic cell lineage in vitro. Notch-1 positive progenitors emerged in the culture of Notch-1 negative granulocyte/macrophage progenitors (GMPs), suggesting that they are more committed to the monocyte/dendritic cell lineage compared to GMPs. Indeed, they highly expressed monocyte/dendritic cell-affiliated genes including SpiB, FLT3, and PU.1. When Notch-1 positive progenitors were cultured in the presence of Notch-ligand (Delta-like 1), their progeny dendritic cells expressed lower levels of CD86 and HLA-DR compared to cells cultured without Delta-like 1, suggesting that Notch signals suppress the activation/maturation of dendritic cell lineage.
