TissueNA
Tissue SpecificityPredominantly detected in hemopoietic tissues and is expressed by monocytes, macrophages, and granulocytes, but not by lymphocytes. Also strongly expressed by dendritic cells (DC);
preferentially by CD14+/CD1a- DC derived from CD34+ progenitors. Also expressed by CD11c+ blood and tonsil DC, but not by CD11c- DC precursors. {ECO:0000269|PubMed:10903717}.
