Abstract

The invention discloses a method for culturing a mini-porcine islet cell in vitro. The method comprises the following steps that a cell growth liquid is prepared; a cell culture liquid is prepared; amini-porcine islet cell cryopreservation tube is taken out, melted and placed into a centrifuge tube containing the cell growth liquid to be centrifuged, a liquid supernatant is removed, the cell growth liquid is adopted to suspend the cell at the bottom of the centrifuge tube, then the cell is extracted into a first culture dish containing the cell growth liquid, and the first culture dish is putinto an incubator for cultivation; after cultivation, the culture dish and a culture medium are replaced, a second culture dish containing the cell culture liquid is adopted for cultivation, and thenthe culture dish and the culture medium are replaced every 1-3 days, and the cell culture liquid is used as the culture medium all the time. The method for culturing the mini-porcine islet cell in vitro can reduce the cell wilting rate, increase the islet beta cell viability, and the cultured cell has a sensitive glucose stimulating response function, so that the method can meet the requirementsfor studying human islet diseases and has important market value and social value.

Description

technical field

[0001] The invention relates to the technical field of animal cell culture, in particular to a method for culturing minipig islet cells in vitro. Background technique

[0002] As the earliest animals raised by humans, pigs have the same omnivorous behavior as humans, but are quite different from dogs (carnivorous) and monkeys (vegetarian). Its physiological function, material metabolism, organ morphology and disease mechanism are very similar to human beings. Pigs and humans have a similar cytochrome oxidase P450 system. The important metabolic enzymatic characteristics determine that the biotransformation of drugs in the body is very similar to that of humans. It is an ideal model animal for drug safety evaluation and screening, and human diseases, especially in anti- Oncology drugs, cardiovascular system drugs, skin-penetrating drugs, non-steroidal antibiotics, and digestive system drugs have shown obvious advantages over dogs and non-human primates.
