Problems solved by technology

"Journal of Guangzhou University of Traditional Chinese Medicine" published an article entitled "Study on the Primary Culture and Sterilization Method of Trichosantherea Cells" in Volume 28, No. 3, May 2011. Although the culture and sterilization method is also a common animal cell culture method, it is found in the culture process and subsequent observation that it has the defects of slow cell division and growth during passage, and is prone to early apoptosis defects.

example 1

[0028] Example 1 (Establishment of the intestinal epithelial cell line of Vermicularis paniculata)

[0029] 1. Reagents:

[0030] (1) Antibiotic combination solution: This combination solution is made by adding penicillin sodium, streptomycin sulfate and gentamicin sulfate to the LBSS solution and mixing. In the prepared antibiotic combination solution, the concentration of penicillin sodium is 200U / ml, the concentration of streptomycin sulfate is 400 μg / ml, the concentration of gentamicin sulfate is 300 U / ml, and the concentration of amphotericin B is 5 μg / ml.

[0031] (2) Thermolysin enzymatic hydrolysis solution: The enzymatic hydrolysis solution is made by adding Thermolysin powder to the HEPES solution with a concentration of 10 m mol / ml, filtering, sterilizing and mixing. The concentration of Thermolysin in the resulting Thermolysin hydrolysis solution is 25 μg / mL.

[0032] (3) Collagenase Type I enzymatic hydrolysate: The enzymatic hydrolysate is made by adding Collagenase T...

Abstract

The invention relates to an intestinal epithelial cell line of pheretima aspergillum. The intestinal epithelial cell line is characterized in that the collection number of the intestinal epithelial cell line is CCTCC-C201294. The population of cells survived in the intestinal epithelial cell line of pheretima aspergillum is high, the cells are high in vitality, and the cell line is high in splitting and growth speed in the subculturing process and can be used for developing medicines or nutrient and health-care products.

Description

Technical field [0001] The invention relates to undifferentiated non-human cells, in particular to an earthworm intestinal epithelial cell line. Background technique [0002] Pheretima aspergillum (E. Perrier) comes from the genus Pheretima aspergillum, and is one of the four original animals included in the "Earth Dragon" section of the 2010 edition of the Pharmacopoeia of the People's Republic of China. Because it is mainly produced in Guangdong and Guangxi, it is called "Guangdilong". Due to its definite curative effect and meticulous processing of medicinal materials, it is recognized as the best quality in the industry. The varieties of Chinese medicine Dilong included in the Pharmacopoeia of the People’s Republic of China also include the dry body of Phetima pectinifera (Michaelsen), Pheretima guillelmi (Michaelsen), and the popular Pheretimav μlgaris (Chen). Called "Shanghai Dragon". Earthworm is cold in nature and salty in taste. It is returned to the liver, spleen and...
