Abstract

The invention provides universal culture mediums and culture method for upper respiratory tract mucosa organs. A liquid culture medium comprises a basic cell factor, a specific cell factor, an inhibitor, penicillin, streptomycin, sterile water and a BEGM culture solution. A gel culture medium is further added with Matrigel with a concentration of 3-6 mg / ml on the basis of the liquid culture medium. The culture mediums are used for culturing upper respiratory tract mucosa tissue organs, are wide in application range, can be used for culturing tissues from various sample sources such as noses, mouths and throats, remarkably improve culture effect, mucosa tissue cell differentiation and cell cilium growth speed, and are beneficial to growth and function maintenance of upper respiratory tractmucosa tissue cells.

Description

technical field [0001] The invention belongs to the technical field of biomedicine, and in particular relates to a culture medium and a culture method for general-purpose upper respiratory tract mucosal organoids. Background technique [0002] The upper respiratory tract mainly includes the nose, pharynx, and larynx. Secretion and cilia are distributed on the inner surface of the upper respiratory tract (except nostrils, posterior pharyngeal wall and vocal cord mucosa), which can warm (or cool), moisten and purify the inhaled air, and have a protective effect on respiratory organs and the human body. The upper respiratory tract plays a very important role in filtering and cleaning the human body. Through the filtering and cleaning function of the respiratory tract, foreign objects such as particles and pathogens that enter the respiratory tract with the air are blocked and removed, and the gas entering the alveoli is almost clean and sterile. These functions are mainly It i...
