Abstract
The invention provides a method for preparing cells. The method adopts equipment for preparing the cells; the equipment is obtained by modifying on the basis of a full-automatic blood component separation machine and is used for culturing and preparing the cells; a weighing sensor is used for replacing an optical grating, and an air inlet device and a liquid sensor are additionally arranged; a connection relation of all devices in the whole equipment is optimized and an operation flow of the equipment is simplified; all steps of all the devices are mutually matched, the production cost is reduced and a technological flow is integrated, so that a cell preparation process is more intelligent and automatic and the operation is more convenient; the pollution to the cells is reduced and the success rate of preparing the cells is improved; the method has a wide 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 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 purpose of curing diseases by reinfusing in vitro screened, modified, induced, and expanded lymphocytes in tissues or blood; common applications include preparation of dendrites Stem cells (DC), T cells, NK cells to treat cancer; prepare Treg cells to treat autoimmune diseases and treat various diseases such as infertility, allergies, and viral infections. ...
