Abstract

The invention provides a cell preparation method. Cell preparation equipment used by the method is modified on the basis of a full automatic blood component separation machine, and is used for cell culture and preparation; a weighing sensor is used for replacing an optical grating; an air inlet device and a liquid sensor are added. The successive application relationship of each device in the whole equipment is optimized; the equipment operation flow is simplified; all steps of each device are mutually matched; the production cost is reduced; the multistep process flows are integrated, so thatthe cell preparation process is more intelligent and automatic; the operation is simpler and more convenient; the cell pollution is reduced; the cell preparation success rate is improved; wide application prospects and huge market values are realized.

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 treatment method of reinfusion into humans or animals; cellular immunotherapy is a rapid development of cell therapy for various diseases in recent years, through reinfusion of in vitro screening, modification, induction, expansion of lymphocytes in tissues or blood Cells achieve the purpose of curing diseases; common applications include preparing dendritic cells (DC), T cells, and NK cells to treat cancer; preparing Treg cells to treat autoimmune diseases and treat various diseases such as infertility, allergies, and viral infecti...
