  2. CD Antigens
  3. Stem Cell CD Proteins

The cluster of differentiation (CD) antigens a protocol used for the identification and investigation of cell surface molecules present on leukocytes. Some CD proteins often act as cell-cell or cell-matrix adhesion molecules, cytokine receptors, ion pores, or nutrient transporters. CD proteins play a variety of roles in immune system function. The stem cells are part of the cells that belong to the stromal tissue. These cells remain in a quiescent state until they are activated by different factors, usually those generated by an alteration in the parenchymal tissue. These cells have characteristic membrane markers such as CD73, CD90, and CD105.
