Abstract

The invention provides a preparation method of PBMC cells. According to the method, equipment for preparing cells is adopted, a weighing sensor is used to replace optical grating, and an air inlet unit and a liquid sensor are additionally arranged. By optimizing the collocation relationship between various devices in the overall equipment and simplifying operation process of the equipment and withthe cooperation of various devices and various steps, the production cost is reduced, the cell separation process is more intelligent and automatic, the operation is simpler, cell pollution is reduced, and the success rate of PBMC cell preparation is raised. The method of the invention has a broad application prospect and great market value.

Description

technical field [0001] The invention belongs to the technical field of biomedicine and relates to a method for preparing PBMC cells. Background technique [0002] Cell therapy is a method of separating and extracting some of the cells from human or animal tissues and blood, and directly infusing them back into humans or animals, or by screening, genetically modifying, inducing differentiation, and culturing and expanding some of the extracted cells. A form of treatment that is infused back into humans or animals. Cellular immunotherapy is a rapidly developed cell therapy for various diseases in recent years. It achieves the goal of curing diseases by reinfusing in vitro screened, modified, induced, and expanded lymphocytes in tissues or blood. Common applications include preparing dendritic cells (DC), T cells, and NK cells to treat cancer; preparing Treg cells to treat autoimmune diseases and treating various diseases such as infertility, allergies, and viral infections. ...
