Web27. nov 2013 · NK cells are a type of large granular lymphocyte that belong to the innate immune system. They are derived from haematopoietic progenitor cells (HPCs) in the bone marrow and express the surface marker CD 56 ( Robertson and Ritz, 1990 ). The HPCs are activated through different stages of maturation to produce CD 56 bright or dim NK cells. WebBased on the case data of a single center, we analyzed the difference of percentages and absolute counts of B cells, T cells, CD4+ T, CD8+ T, and natural killer (NK) cells in the peripheral blood of patients with endometrioid endometrial cancer (EEC) and patients without cancer, and we analyzed the difference of lymphocyte subsets in different ...
