CD13／APN不仅是髓细胞表面标志,也分布于其它多种体细胞,具有重要的生物学功能。近年来的研究主要集中在其促血细胞分化发育、参与血管发生、调节免疫应答以及作为细胞表面受体发挥作用等方面。虽然其中很多环节的分子机制还有待进一步阐明,但CD13／APN已经显示出应用于科研和临床治疗的良好的潜力。 CD13 / APN is not only the surface markers of myeloid cells, but also distributed in many other somatic cells, which have important biological functions. In recent years, the research has focused on the development of hematopoietic cells, the development of blood vessels, the regulation of immune response, and the role of cell surface receptors. Although many of these molecular mechanisms remain to be elucidated, the CD13 / APN has shown great potential for research and clinical treatment.
