自然杀伤细胞(Natural Killer Cell，NK)是机体重要的免疫细胞，来源于骨髓淋巴样干细胞，发育成熟依赖于骨髓和胸腺微环境，主要分布于外周血和脾，不表达特异性抗原识别受体，目前临床将TCRˉ、mlgˉ、CD56+、CD16+淋巴细胞鉴定为NK细胞。NK细胞可用于癌症防治和改善机体免疫功能。
NK cells platform
Natural Killer Cells (NK) are important immune cells in our body. They are derived from bone marrow lymphoid stem cells, fully developed by spinal marrow and thymus microenvironment, and mainly distributed in peripheral blood and spleen. It does not express specific antigen recognition receptors. Currently, TCR ˉ, mlg ˉ, CD56 +, CD16 + lymphocytes are identified as NK cells clinically. NK cells can be used for cancer prevention, be of potential for cancer treament, and improvement of immune function.
Features and functions
1. Nonspecific, therefore, broad-spectrum of tumor cell killing activity;
2. Secrete a variety of cytokines upon activation, therefore, may function in immune-system
adjustment in vivo;
3. May inhibit, in vivo, tumor micro metastasis, reduce recurrence and development;
4. Improve cancer patients’ living quality, elongate patients’ survival term.
Highlights in our technology/products
1. Our protocol does not use human tumor cells or transformed cells as trophoblastic cells in
NK cell culturing, so it is safe;
2. Our preparations consist of high purity, high activity of NK cells, and therefore highly
effective in anti-cancer.
