Abstract

The invention discloses a primary culture method for alveolar epithelial cells of Microhyla ornata. The primary culture method comprises the following steps: subjecting adult Microhyla ornate to surface sterilization; dissecting the adult Microhyla ornate, taking out the lung and carrying out cleaning with a HBSS balanced salt solution; adding a collagenase I solution for digestion; subjecting a digested solution to refrigeration and centrifugation and adding a complete cell culture medium; blowing and beating the fragments of the lung tissue, and then carrying out filtering by using a cell filter screen with a pore diameter of 100 [mu]m so as to obtain a cell suspension; and subjecting the cell suspension to culture at a constant temperature of 27 DEG C and replacing the previous completecell culture medium with a new complete cell culture medium every 3 to 4 d. The primary culture method of the invention can rapidly and repeatedly establish primary culture of the alveolar epithelialcells of Microhyla ornate; needed cell culture equipment is simple and has good operability; and acquired cells have obviously faster growth speed than the alveolar epithelial cells of mammals. The prepared alveolar epithelial cells of the invention significantly supplement existing alveolar epithelial cells of mammals and provide a novel cell material for research on major biological and medicalproblems such as terrestrial adaptability, lung development, pulmonary fibrosis and tuberculosis.

Description

technical field [0001] The invention belongs to the technical field of animal cell culture, and in particular relates to a method for primary culture of alveolar epithelial cells of Rana adenocarpus. Background technique [0002] In 1907, Harrison used the hanging drop culture method to culture frog embryonic neural tissue in a lymphatic clot for several weeks, and observed that axons grew from the cultured tissue block, thereby creating a cover sheet covering The dimple glass hanging drop culture method has laid the foundation for the in vitro culture of animal tissues. In 1913, Carrel introduced the strict aseptic technique in surgical operation into the in vitro culture of animal cells, enabling the cells to grow in vitro for a long time. In 1916, Rous and Jones applied trypsinization to tissue digestion and cell passage, marking the beginning of real animal cell culture. In 1948, Earle isolated and continuously subcultured the first cell line from the subcutaneous tiss...
