Netravali, Ilka Arun. 2014. Elucidation of plasmacytoid dendritic cell development. Doctoral dissertation, Harvard University.Abstract
Most currently defined hematopoietic progenitor pools are heterogeneous, contributing to uncertainty regarding the development of certain blood cells. The origins of plasmacytoid dendritic cells, for instance, have long been controversial and progenitors exclusively committed to this lineage have never been described. We show here that the fate of hematopoietic progenitors is determined in part by their surface levels of 9-O-acetyl sialic acid. Pro-plasmacytoid dendritic cells were identified as lineage negative 9-O-acetyl sialic acid low progenitors that lack myeloid and lymphoid potential but differentiate into pre-plasmacytoid dendritic cells. The latter cells are also lineage negative, 9-O-acetyl sialic acid low cells but are exclusively committed to the plasmacytoid dendritic cell lineage. Levels of 9-O-acetyl sialic acid provide a distinct way to define progenitors and thus facilitate the study of hematopoietic differentiation.Terms of Use
