CD105 belongs to cell membrane glycoprotein and shows a specific expression status on both tumor tissue and surrounding vascular epidermal cells, and a study by Metcalfe et al. showed that the microvessel density (MVD) marked by CD105 is closely related to the clinical stage and prognosis of cervical cancer patients [9], which may provide a theoretical basis for cervical cancer treatment. Here, ENG is linked to neoplasm.
