Abstract

The invention discloses a primary culture method for salivary gland cells of Hirudo nipponia, belonging to the field of bioengineering technology. The method comprises the following steps: inoculating an enclosed cell culture flask having a volume of 25 cm<2> with scissored tissue blocks; adding 5 mL of a SFX-INSCET insect cell culture solution; and placing the flask in a biochemical incubator for static culture at a temperature of 29 DEG C. The method provided by the invention substantially increases the output of natural hirudin; and a great number of salivary gland cells can be obtained after in-vitro cell culture of a tiny number of salivary gland cells of wild Hirudo nipponia, and a great amount of natural hirudin is separated and extracted, so wild Hirudo nipponia populations are protected, deep development and utilization are realized, and the germplasm resources of animals are substantially protected. The method is rapid, effective and repeatable, improves culture of leech cells and provides reliable test data and foundation for research on primary culture of leech cells.

Description

technical field [0001] The invention belongs to the technical field of bioengineering, and in particular relates to a method for primary culture of Japanese hirudo salivary gland cells. Background technique [0002] With the rapid development of life sciences, cell culture is an essential process for both the entire bioengineering technology and one of the biological cloning technologies, and promotes the development of cell biology, molecular biology, biochemistry development in other fields. Japanese medical leeches (Hirudo nipponia) belong to the phylum Annelids, which include the subphylum Annulus, class Hirudo, order Hirudo nipponia, family Hirudo, and genus Hirudo. According to statistics, there are more than 600 species of leeches distributed all over the world, and nearly 100 species are distributed in my country. They live in rivers, wet land, and fields. Some live by feeding on the blood of mammals such as fish, frogs, water birds, cattle, horses, and humans, and...
