Based on the health industry, focusing on national health. On 29 December 2023, Weihai Ziguang was officially approved as "Key Laboratory of Cell Preparation and Storage in Weihai Economic and Technological Development Zone", and this important progress marks Weihai Ziguang's solid step in the field of cell technology and regenerative science, and it also marks the beginning of Weihai Ziguang cell technology project.

    Weihai Ziguang Cell Preparation Centre, supported by professional talents, is based on the three major fields of stem cell preparation, immune cell preparation and cell storage, and carries out a number of services such as stem cell and immune cell preparation and storage with professional technology, constructs 2000 square meters of B+A grade GMP cell laboratory, which provides a high-standard environmental guarantee for cell preparation and storage, and builds a complete cell preparation and storage technology service system. Through technology introduction and independent research and development, we have established a complete technical service system for cell preparation and storage. In addition, Weihai Ziguang has established a strict inspection, release and review system to ensure the quality and safety of cell preparation and storage. In terms of process standardisation, it strictly follows the international standard production process and operation standard, aiming at zero defects and strict quality control.

    Weihai Ziguang Cell Preparation Centre has built four platforms, which contains immune cell preparation, stem cell preparation, cell quality testing and cell storage, covering the whole process of cell preparation and storage, and can carry out the preparation and storage services of clinical grade stem cells and immune cells from peripheral blood, umbilical cord blood, umbilical cord and other tissue sources. The perfect platform planning enables Weihai Ziguang to have strong competitiveness and market influence in the field of cell preparation and storage.

    Weihai Ziguang Cell Preparation Centre is equipped with advanced instruments and equipments abroad, including biosafety cabinets, CO2 incubators, inverted microscopes, cell counters, cryogenic freezing centrifuges, ultra-low-temperature refrigerators, etc., which provide highly efficient and accurate technical support for cell preparation and storage, and satisfy the diversified needs of cell technology development and cell production.

    With the formal approval and establishment of the Key Laboratory of Cell Preparation and Storage, Weihai Ziguang will continue to increase R&D investment and promote the innovation and development of cell preparation technology. At the same time, Weihai Ziguang will also strengthen the cooperation and exchange with domestic and foreign research institutions, and jointly promote the rapid development of the cell technology industry.

    Looking into the future, Weihai Ziguang will continue to adhere to the concept of "innovation, quality, service" and make greater contributions to the cause of human health.

NK cell wikipedia:

NK cell is a type of lymphocytes, which can be divided into T-lymphocytes, B-lymphocytes and NK cells.NK cells, also known as natural killer cells, are important cells that make up the body's immune system and are derived from the bone marrow, which accounts for about 15 per cent of the total number of leukocytes in the blood.NK cells are found in the peripheral blood circulation, as well as in the liver and the spleen in the normal body.NK cells have the function of identifying aging cells in the body and are capable of phagocytosis and killing them. NK cells have the ability to identify aging cells in the human body, and can phagocytose and kill them, as well as identify pathogen-infected cells and abnormally proliferating tumour cells, and can also phagocytose and kill these cells. In addition, if NK cells are activated, they can also secrete perforin and tumour necrosis factor to attack the infected or mutated cells, so NK cells are a line of defence for the human body to resist infection and malignant tumours. In addition, research has also found that NK cells can also participate in hypersensitivity reactions, and even affect the occurrence of autoimmune diseases.
