Abstract

The invention discloses a novel highly efficient method for preparing a mice pancreatic single cell suspension. The method comprises the steps of selection of mouse pancreas, cold digestion of pancreatin, separation and purification of pancreatic single cells and the like. The key technology of the method is that: the pancreatin is used for invading the pancreatic tissue under conditions of low temperature and low activity, and the pancreatic tissue is dissociated by a short warm digestion so as to obtain the pancreatic single cell suspension with high quantity, high purification, high activity and no adhesion. Compared with the common pancreatic cell separation method, the method of the invention has the characteristics of stable operation, high cell yield, high cell activity and the like, avoids the defect existing in the common pancreatic cell separation method that the pancreatic cells are damaged due to long-time warm incubation of the pancreatin, the DNA released when the cells are died in large quantity is wound so as to cause the cell adhesion and the like, solves the problem of difficult separation and analysis of the pancreatic single cells and lays a foundation for further using the pancreatic cells.

Description

technical field

[0001] The invention relates to a novel and efficient technology for separating and preparing mouse pancreatic single-cell suspension, in particular to a method for separating and preparing high-activity, high-purity, and non-adhesive pancreatic single-cell suspension by adopting a trypsin cold digestion method. Background technique

[0002] Diabetes mellitus is a metabolic disease characterized by hyperglycemia caused by the lack or dysfunction of pancreatic β cells. In recent years, with the development of social economy and the improvement of residents' living standards in various countries in the world, the incidence and prevalence of diabetes have increased year by year. Diabetes not only affects the quality of life of patients and brings a heavy psychological burden to patients, but also the complications of diabetes pose a threat to the health and life of patients.

[0003] Pancreatic stem cells are a type of pluripotent cells with high proliferation ...
