Novel activating receptors of the lg super-family expressed on human myeloid cells, called TREM(s) (triggering receptor expressed on myeloid cells) are provided. Specifically, two (2) members of TREMs, TREM-1 and TREM-2 are disclosed. TREM-1 is a transmembrane glycoprotein expressed selectively on blood neutrophils and a subset of monocytes but not on lymphocytes and other cell types and is upregulated by bacterial and fungal products. Use of TREM-1 in treatment and diagnosis of various inflammatory diseases is also provided. TREM-2 is also a transmembrane glycoprotein expressed selectively on mast cells and peripheral dendritic cells (DCs) but not on granulocytes or monocytes. DC stimulation via TREM-2 leads to DC maturation and resistance to apoptosis, and induces strong upregulation of CCR7 and subsequent chemotaxis toward macrophage inflammatory protein 3-β. TREM-2 has utility in modulating host immune responses in various immune disorders, including autoimmune diseases and allergic disorders.

The invention relates to an optimal method for efficiently separating and expanding mesenchymal stem cells in umbilical cord blood in cell therapy. The fact that the mesenchymal stem cells with higher differentiative capacity and smaller immunological rejection are contained in the umbilical cord blood has been proved. The establishment of an umbilical cord blood bank provides a basis for achieving transplantation of autologous cells. However, since the content of the mesenchymal stem cells in the umbilical cord blood is very low (only 0.5 to 30 mesenchymal stem cells are contained in 1*108 mononuclear cells), how to efficiently separate and expand the mesenchymal stem cells becomes a problem hindering the transformation of the mesenchymal stem cells in the umbilical cord blood to the clinical application. At present, in most situations, the mesenchymal stem cells in the umbilical cord blood are separated in virtue of adsorption capacity of the mesenchymal stem cells in a culture vessel, but the success ratio is low, and the characteristics of stem cells are difficult to maintain in an expanding process. The method comprises the steps of coating the culture vessel with protein components, adding multiple growth factors in the culture vessel in a coordination manner, and building the expansion environment of the mesenchymal stem cells in the umbilical cord blood, so as to achieve the efficient separation and expansion of the mesenchymal stem cells.
